In the thermal imager we can not see

107
Progress in the field of military technology every year gives out some innovations. For example, several years ago, suitable for use on helicopters, armored vehicles, and even rifle rifles. weapons thermal imagers. The thermal imager senses the heat flux from a heated object, which in the eyepiece of the device looks either white if the device is black and white, or red if the device is colored.




The U.S. Army experienced thermal imagers during the second Iraq war and was uncontrollably delighted with them. Silhouette silhouette at night on the background of a cooled desert tank It was clearly visible for miles - so that it was possible to point weapons in the thermal image. After such success, the U.S. Army began to buy thousands of sensitive thermal imagers. In addition, under contract, BAE Systems creates a combined night vision device and a thermal imager in the form of glasses for the US Army. The development of these points received a budget of $ 434 million.

As the combat experience of using thermal imagers was accumulated and clips appeared on the Internet, which demonstrated how a helicopter with a thermal sight shoots the enemy, as if on a testing ground, a kind of “thermal fear” gradually began to spread. They say that Americans equipped with thermal sights, can shoot the enemy at night, as if in a dash. Of course, all this was tried on the Russian army, which so far lacked the same number of thermal imaging devices, and from this they made sentimental conclusions: that the Americans could win us in the war.

Thermal imager gives tactical advantages

However, despite all the advantages, the thermal imager is still a rather rare thing even for the American army, in which, by the beginning of 2012, about 13 of thousands of thermal imaging devices were supplied. Helicopters and armored vehicles are already equipped with them, but the infantry has so far not much thermal imagers. The reason is a rather high price, a lot of weight (the lightest device for small arms weighs 1,7 kg, and the machine gun thermal sight weighs 3,2 kg), as well as difficulties with power supply. In addition, compact thermal imagers do not have matrix cooling systems, so their range, resolution and image clarity are far behind helicopter sights.

However, even if there is only one reconnaissance thermal imager in the platoon (like French Sophie binoculars weighing about 2 kg and a person's identification range in 1200-1300 meters), and the machine guns are equipped with thermal sights, this gives a significant advantage over the enemy in night combat. Thermal imagers allow you to see the position and movement of the enemy, adjust the machine-gun fire and inflict losses from the maximum firing range, and then the infantrymen with usual night vision devices will finish the job.

In general, with the development of night-time devices, a trend has appeared: up to 70% of fire contacts occur at night. This is understandable: the side equipped with night-time devices is trying with all its might to realize its technical advantage.

So the question of the use of thermal imagers should not be underestimated. Even if the enemy has a few of them, you can be defeated. However, there is also a tendency to exaggerate the capabilities of thermal imagers, which is clearly used for propaganda that suppresses the morale of the likely adversary. “Thermal Imaging Fear” is clearly deliberately bloated. But we have already passed. At first, a new weapon always caused such a “fear” until the means of counteraction were found.

From polycarbonate to padded jacket

As soon as it became clear, the domestic “survivalist” public began to intensively wiggle their brains on how to overcome the newest technology of a potential adversary with something simple, like a brick. Although by themselves the survivalists often cause only the smile of many of their naive ideas, we must nevertheless pay tribute: it was precisely in the matter of deceiving the thermal imagers of the potential invaders of their native forests and marshes that they were able to go far ahead. Everything was done according to science. Brainstorming was organized on the forums, and then the suggestions made were tested in marching and combat conditions with the help of a hunting thermal imager. Though not as good as a helicopter thermal imaging sight, it nevertheless made it possible to assess the capabilities of the equipment and the invented means of its deception. The findings were illustrated with photographs.

Dozens of rational proposals from national inventors were expressed and tested, without much exaggeration. The result was stunning, so to speak.

It turned out that the simplest and most improvised materials quite easily block the thermal radiation from the body, perceived by the thermal imager, which allows either to disguise (in the device under the disguise a dark spot can be seen where the person hid), or to strongly blur the contours of the heat spot. The latter is also very important, since to make it difficult to recognize the target is as important as to hide from the opponent’s gaze completely.

The first. There are many materials that block thermal radiation. These include glass that can hide heat even from a very sensitive sensor and at close range, almost point blank. An excellent result showed a light sheet of cellular polycarbonate, no worse than glass. Surprisingly well made ordinary polyethylene, transparent to thermal radiation. The polyethylene film, of course, did not completely cover the heat source, but on the other hand, it greatly eroded its contours. Among the human vegetation under a plastic wrap would be very difficult to see.

The principle was simple. Any material that heats up badly, does not re-radiate and does not reflect heat is suitable for blocking the thermal radiation perceived by the thermal imager. The worse the thermal conductivity of the material, the better. For example, a neoprene wetsuit looks black in a thermal imager. One of the participants in the brainstorming made a surprisingly simple and effective thing - an anti-thermal mask on the face. He took food foil and polyethylene, shifted them in several layers and pierced for strength. Then he took a piece of tourist foam (usually foamed polyethylene or ethylene-vinyl acetate), cut two narrow slits for the eyes in it, and attached the above-described heat reflector outside. After walking a few minutes in it so that the whole structure warmed by body heat, he took a picture on the thermal imager. On it, the face was covered with a black square, in which two slits for the eyes were burning brightly, like in an alien. The author of the development says that the slits for the eyes can be closed with glass. It seems that the good old cotton gauze mask from the Soviet textbook on civil defense will show not the worst result.

The second. Field tests were carried out in conditions of dense vegetation, shrubs and especially reeds. It turned out that the thermal imager of a person does not distinguish between reeds. Heat flow is blocked by reed stems in which water circulates, which creates a cooled screen. The same can be said about the thick grass, dense foliage, dense shrub. All this is a barrier beyond which the imager is difficult to see something. Survivors of this cheered. If Americans try to comb our forests at night, which have thick undergrowth, the imager will not help them much in this. Nevertheless, Russia is not Iraq, and the conditions are different here.

From this it was concluded that all kinds of shields and shelters of reeds, as well as of plywood can be quite effective masking from the thermal imager. This may be, for example, the most common, dense reed mat. The main thing - do not warm it up with the warmth of your body.

Since the climate of Russia is somewhat different from Iraq, and there are such weather phenomena as rain, snow and wet fog, it was found that this also helps against thermal imagers. The water in a plastic bottle, for example, completely hid the heat from the heated soldering iron. A wet cape, for example, a cloak, hides the heat is not fully, but it is very noticeable blurs the heat stain, making it difficult to recognize. In the wet rain forest from the imager will be of little use.

Third. Not bad mask from the imager, some types of clothing. Judging by the recall of experimenters, classical samples turned out to be the best: quilted jackets, wadded pants, jackets. The fur has shown itself quite well, but not everyone. Better fit fur with a hollow hair, to the greatest extent heat insulating.

American strategists can grind their teeth: a padded jacket protects Russians here too. Vodka can also be a means of protection. In the cold, even a small amount of alcohol leads to a narrowing of the peripheral vessels of the body, which leads to the fact that the extremities cool and become less noticeable in the imager. You can cover the whole body with protection, but brightly glowing warm hands can give a person, especially close. The main thing - do not get involved and remember the danger of frostbite.

But this is not all discovery. From the most remarkable, it turned out that a conventional umbrella is a very effective tool against a thermal imager. Under an open umbrella, the person in the imager is not visible. The umbrella blocks the heat flux from the body, but it does not heat up on its own and does not re-radiate heat. The same effect has a tent, and indeed any cloth shed, located at some distance from people.

Thermal imaging shield

Thus, the efforts of the public have shown that the imager can be rendered useless by the simplest means made from scrap materials. You can easily disguise yourself in a position, close a firing point or a sniper's position from thermal detection. If desired, you can hide from the detection of the imager even in motion. It will require a growth shield, suppose of polycarbonate or light plywood, which the fighter carries in front of him with his left hand, for which a special belt fastening is made on the shield (necessarily insulated from the shield). A shield is made in the shield for observation, covered with transparent plastic or tempered glass. The shield itself must be camouflaged from visual observation: camouflage coloration and the stems and branches attached to it.

Tactically, such a shield is most applicable, firstly, at night, and secondly, in combination with other obstacles, such as trees, bushes, buildings (but we must remember that stone buildings, heated by the sun, glow at night in a thermal imager and can be unmasked who will pass on their background). It is better to move with him by attaching steps, making sure that the shield does not move the branches of trees and bushes (this will be seen in the imager). You can kneel down and put a shield in front of you, you can lie down and lay it in front of you or cover yourself with it. To shoot, you need to turn a little to the side, holding the weapon ready, but after the shot (even with PBS; in the imager, the weapon warmed by body heat and shots will burn with a bright spot) you must immediately change position and hide yourself with a shield. It is also necessary to remember that frequent shooting from behind the shield will soon lead to the fact that hot powder gases can form a bright halo in the imager around the shield. So it is desirable to change the position as often as possible.

The possibility of creating a special insulating equipment that dramatically reduces the visibility in the imager is also being discussed. It is possible that such a kit can be created and it will be effective. But it is unlikely to be widespread. Most likely, it will be used in special forces and intelligence. For the rest of the army, simpler and more accessible means of thermal disguise, such as the shields described above or fabric bed curtains and capes, will remain, especially if this is a mass army.

    About five years ago, they also played such a "survival", The best result is a shopping mall trimmed with an umbrella.
    Shields - a hat. Do not get fooled. The halo from breathing is visible even in the hunting thermal imager, the risk of illuminating the limb is at 100%, especially when moving along the intersection.
    From close breathing, the shield will heat up very soon ... It is important to maintain the distance to the shield and God forbid you touch it with your hands (fingerprints glow)


    (The size of the umbrella is at least 2x3 meters, at least less, if you need less sailing, or walk closely in the forest with umbrellas)

    PS What is characteristic - the "camouflage umbrella" itself must first take the ambient temperature, otherwise if it is colder, then you will walk in a black square, visible for hundreds of meters)

    That's what came to mind: two-ply clothing. Between the inner and outer layers, there is a perforated plastic net that wears just like clothes. Between the inner and outer layers of the air pump, air is pumped from the environment. Air is a good heat insulator. Having managed to warm up from the inner layer of clothing, the air is removed by the pump into the atmosphere, and its place is immediately taken fresh. Have but". The air heated up from the body at the outlet will need to be cooled, otherwise it will “sound” on the thermal imager screen. Pass heated air through Peltier elements? Technically possible ... Of course, there are other "buts" and their mass. But a person’s life is one, and it’s better to break your head today than to lose it tomorrow.

      Better not a net, but a plastic film coated with sprayed aluminum or silver. In the article, by the way, this is examined: "He took food foil and polyethylene, put them in several layers and stitched them for strength.". Recall the school physics course. The black body, which is the standard, emits the most. An ideal mirror does not radiate at all, no matter what temperature it has. It is easy to verify this by trying to measure the temperature of the polished metal surface with a pyrometric IR thermometer.
      Heated air practically does not radiate due to low density. Breathing is only visible due to heated exhaled water vapor.

        I, in principle, do not mind. I had a purely practical suggestion ... Have you ever had to run in chemical protection? Not even that. Running, sweating, and then in all this for some time to conduct a reasonable activity? I assure you: in “polyethylene” you “boil” in the summer, and in winter your clothes under such a film are very quickly absorbed by moisture, and instead of a heat insulator they become a conductor of cold - you will freeze, and hard. Steam should be diverted from the body, and this is best done with ambient air. According to the principle of "cooling jacket" in an internal combustion engine. But a person cannot afford such luxury as wearing liters of water on himself to cool himself, I repeat, the surrounding air will do it best. To do this, ventilation ducts are made in the "grid" ... The idea, in general, is not new and has long been used in space suits.

          You must have seen modern Alaska jackets with a silver lining. This is an implementation of this particular principle. Thermal insulation. If the fabric is covered with aluminum threads, then such a fabric "breathes".

          And with regard to checking the effectiveness of protection, I liked my own idea of ​​checking with a pyroelectric IR thermometer. Such devices are now inexpensive and cost around 1K rubles. It is much cheaper and more affordable than a thermal imager.

            The tissue will heat up from the steam produced by the human body. This is physics, unfortunately ... condensation will form on it from the inside, even just lying in an ambush in such a “outfit” will not be comfortable, but in winter it will be like death. While a person lives, he soars. In a sense, it produces heat and moisture. These two factors must be cut off. So that the temperature of the upper layer of clothing is equal to the temperature of the air. Even a half-degree difference will be noticeable in the thermal imager, while combat samples have even greater sensitivity. I summarize: then the person will not be visible in the thermal imager when the "temperature" of the person becomes equal to the temperature of the air surrounding him - no more, no less. If this is not a corpse, then the most technical simple solution is a two-layer clothing with forced air circulation between the layers. At least I'm convinced of that. Maybe I'm wrong. Need to try.

              In fact, you are right. But the question arises: where to put the "exhaust"? Plus, any forced circulation pump will warm up. Try touching the exhaust hose of a car compressor. Any compression heats the air. This is elementary thermodynamics. Therefore, what will “shine” more is still a very big question. In general, this is a good engineering task for optimization.

              By the way, a good "thermal imager" can be made from an ordinary digital camera. To eliminate color distortion, manufacturers specifically mount an IR filter there. If you remove it and put a filter for the visible spectrum, you get a "thermal imager". Canon, by the way, at one time produced special cameras with a remote IR filter. They had an “A” index and were used for astronomical surveys.

                where to put the "exhaust"?

                I talked about this. Heated air can be tried to pass through a "refrigerator", consisting of groups of Peltier elements. An electric current will be required, however, as for the operation of an air pump ... The problem is this. The “exhaust” air must be at ambient temperature. At a positive temperature, theoretically, this can be achieved by throttling (although I still have no idea what this unit will look like); at negative temperatures, everything becomes much more complicated - the moist air will give up its moisture with frost on the cooling elements, and their performance will deteriorate significantly, therefore, should the moist air be drained somehow ... pass through silica gel? In general, it is not a trivial engineering task. In such a scenario, a fighter would have to carry a whole satchel with a battery, an air pump, a refrigerator, a dehumidifier behind him ... which, in fact, is observed by the astronauts. One joy - an oxygen cylinder does not have to be taken with you ...

                  But Peltier also has efficiency, and very low. One side he cools, but the other heats up much more. Understand, as soon as you put something for cooling, a surface will surely appear, which heats up much more strongly than the cooled one. The principle of the refrigerator. And the battery from which energy is taken is also heated. In general, as soon as you put some additional devices for cooling, the question arises: how to suppress your own IR radiation from these devices?

                      There is a way of cooling. Self-cooling gas flowing from a high-pressure tank. But, for this case, it is hardly possible to build a reasonable system with acceptable operational characteristics.

                    No, germanium "optics" cannot be replaced by glass-mirror ones. The word optics is not casually quoted here. A “lens” made of thin-walled germanium well transmits infrared rays of the desired wavelength, a glass lens will absorb them, and a strong signal attenuation will occur. For this reason, the "optics" of some thermal imagers are black and not transparent. That is, in the visible range of light wavelengths, nothing will be visible through it. The image on the monitor screen will be drawn by a microprocessor, which receives a signal from a sensitive sensor - a bolometer. Another type of thermal imager has yellow optics made from zinc selenide, if I'm not mistaken. The principle is the same, only the sensor is not a bolometer, but some other ... forgot. There it’s all about the wavelength, your sensor for the right range.

                A thermal imager can be made from any digital camera and this is used, for example, in a virtual viewing system in flight simulators. The program that works with such a camera is called TreckIR, that is, an infrared tracker. However, instead of a filter, you still need to insert a lighted film or, more realistically, an X-ray film.

                    There is still the possibility of changing the concept.

                    At the moment when you are sure that you are caught in the light or at the time of an active battle, you can scatter heat traps.

                      Theoretically, yes. But practically ... before the shooting you will not understand that you are "grazed". A person or group of people will be viable until they are discovered, after which they will be destroyed. If a group is “covered” with mortar fire, how will thermal traps help it?

We will heat some places in Europe and the USA to 1000 degrees - you look, and thermal imagers will not be needed in Berlin. winked The main thing here is that the red-hot metal from the machine does not drip onto the breech pants. .All are fighting, poor thing.

But in such positions, pipes with heat dissipation and all sorts of things would be just right so that there would be a full light in the thermal imagers and that the fighters would not glow in the dark when controlling the terrain.

    Any scientist associated with electronics understands that the question is not only that modern thermal imagers can be contrasted with simple and home-grown protection methods. The question is that the enemy has created technologies for mass production of devices on which the process of improving these technologies is ongoing. Therefore, Russian students are thinking what clay to cover their faces or with foil to cover themselves, and American inventors and students are thinking how to increase the energy density on element devices. to see not the heat itself in its primitive term, but to see the potential of a person in all his guise and not only in direct rays, but also reflected in the same leaves and all attributes of the area, as well as through the metal of cars and tanks.

            You are right that on the modern element base and the devices that we now have, they are really not able to clearly perceive and in only one vector the potential of not only a person, but everything that stands or moves. However, that’s why I’m talking about new devices which, in addition to transistors of induction coils, etc., are an absolutely independent type of element series of these devices. These are devices that allow you to create ultra-high density of magnetic fluxes. These are new induction coils without the effect of self-induction. What does it give? This will create the potential of resultant interactions that can fix exactly the level that corresponds to such an interaction. After all, when sending a signal of an electronic magnetic pulse through a radar, we must obtain the same parameter of the electronic magnetic disturbance. But having created it on our device, we can perceive it in a one-sided vector. Therefore, without the technology and knowledge of how to create energy density, and even more so through which tools it is really useless to dream about it. But not now.

                First, pick up the beat and don’t have to yank me, where I entered or did not enter. Let it not bother anyone. . Secondly I try to be understood. that many physical processes, for example, the same changes in the properties of a semiconductor, can be carried out by placing it in a magnetic field with certain and specified control parameters, which will change the parameters of this semiconductor. In other words, in principle, it is completely obvious that it is possible to change the properties of any substance in general by how and how we can create a radial magnetic field in it with given parameters of certain magnetic fluxes in it. Therefore, the resonance for many is a parameter of some abstraction justifying an extreme burst of email. magnetic impulse. But in fact it is a process described mathematically as combining some algorithmic processes with others. Or in other words, when some mathematical flows of numbers in their algorithm for describing a particular process are combined with another process. Well, let me be a fool and stop. In general, these are elements of complexity and new methods of working with unlimited large mathematical data. In general, one cannot tear off the methods of analysis from how and where to apply them and use theory and analysis with the practice of embodiment.

    In the cold, even a small amount of alcohol leads to a narrowing of the peripheral vessels of the body, which leads to the fact that the limbs are cooled and become less noticeable in the thermal imager.

    This is a school curriculum. Alcohol, on the contrary, dilates blood vessels. And here on the site everyone at least once in a lifetime, but drank and in practice knows this matter.

    It is impossible. The person will not be visible, a moving shield will be visible. It’s all too early to get in a car, close the windows and go “unnoticed” behind the glass. Or move around in the tank. The enemy is, of course, stupid and will not guess that a man is sitting in the car.

                I remember reading with Cruise. Normally, something is visible when the temperature of the area is stable. But for example, after sunset on heterogeneous terrain, some parts cool faster, others slower. For example, a stone cools longer than sand. And the sand in different parts of the terrain cools differently. Due to this, spots appear and flicker. The picture becomes unreadable and this business continues for a rather long time.

                It is, but moving objects are clearly visible either against the background of dark spots, then against the background of light spots.

    The thermal imager, thermal imager ..... my wife sees me through and through without the thermal imager! (so she says ... recourse ) Now so much “attention” is being paid to neutralizing the “infrared threat” that the military is already scratching turnips, fearing that the time will soon come when the efficiency of infrared devices will rush to 0 ... Thermal imagers will see not only objects whose bodies are heated more than Environment; but also, on the contrary ... Therefore, it is not in vain that special attention is paid to the development of tools (panels, cloaks, "foam", aerosols) that shield the object's own thermal radiation and "imitate" the thermal radiation of the environment. But paying special attention to the IR range, we forgot about the UV range! Often, uniforms, object protective equipment that protect well in the infrared range, "glow" in the UV range! Especially, UV devices (observations, detections, visions, sights) are "asking" for the Arctic! There, the UV component of sunlight is higher, and the reflection of UV radiation from snow is stronger ... By the way, reeds, grass ants were mentioned ... so ... green foliage reflects only 7% of ultraviolet (UV), sand in the desert can reflect 3% UV, and many camouflage fabrics can be much larger. For example, a sniper suit (gilly), invisible in the visible optical range, is clearly visible in UV. Moreover, UV devices are simpler and cheaper than IR devices.

    We had a case in Kazan, a young guy made a robbery at night and hid in the bushes in Victory Park, by the way the bushes were near the lake. The Kamovka pinwheel of the Ministry of Internal Affairs flew in with a thermal imager and quickly found the criminal, the ground group easily detained him when coordinated from a helicopter!

    There is also a tendency to exaggerate the capabilities of thermal imagers, which is clearly used for propaganda that suppresses the fighting spirit of a potential enemy. "Thermal imaging fear" is clearly deliberately inflated.

    Spirit of the spirit, but for example in Iraq there were practically no attacks on American soldiers at night. Because Iraqis against the Americans with their night sights and thermal imagers were like blind kittens.
    Surprisingly, ordinary polyethylene, transparent to thermal radiation, performed quite well.

    In Chechnya, militants hid from our night reconnaissance equipped with a thermal imager using a plastic wrap. Hearing the rumble of a helicopter, they covered themselves with a cloak. For a short time, it really saved from detection.
    Shields can of course be made, but moving with it is unrealistic.

      Water should level the temperature difference well. First, due to heat capacity, then due to evaporation. Both this and the other consume a lot of energy. whereas in the case of air cooling, all this energy will be used to increase the air temperature. In dry air, somewhere in the desert, you can get the opposite effect - a dark spot. But the forest should work well. That's just a problem with breathing, through it almost half of the body's heat production is diverted. I think a gas mask with a trunk shoved under clothes will help. At the same time, his eyes partially mask. So that there is no silhouette, you can spray water with stains from a spray bottle. At the same time, a spray gun will help to help you choose the right dose so as not to overheat and not to overcool.
      In general, I think that the main cheap method of reducing visibility in the thermal imager will be a spray gun screwed directly onto the flask, plus some recommendations on how to use it depending on clothing, temperature and wind. It would also be nice to cover the gas mask with something water-holding so that the water does not drain and evaporate. And it would be nice to replace the glass with heat-insulating ones - double or plastic, so that they do not heat up and do not shine themselves.

          In winter, the task is more difficult. Too much temperature difference. Any error becomes clearly visible. And at the same time easier - snow is a good insulator and absorber at the same time. Those. buried in a snowdrift - only breathing remains, which again can be passed through the snowdrift, digging a passage there.

          Then pouring water makes no sense, and so at least wring out the equipment. And to cover with a film does not help - it warms up quickly. But the film can be sprayed from the inside. Then her temperature will decrease, and the necessary spotting can be given.
          Or is it about stealth in motion? Then a bummer. There are no cheap ways to disguise themselves in principle. The Israeli comrade in the subject confirmed - the movement of people is noticeable even in the conditions of moving spotted chaos that occurs after sunset.

    in the news, there was a film for windows ("dielectric-silver-dielectric") with a coefficient. 70% infrared rays of the long-wavelength NIR and VLT reflection spectra. In general, silver and its compounds
    such advice at the front
    If you don’t have a specialized foreign uniform, the easiest way is to put on cotton pants, a quilted jacket, thick gloves and a multi-layer balaclava, under your clothes - thermal underwear, better composite, which is made of various materials, synthetic and natural. But we must remember that over time the clothes will warm up and become noticeable to the thermal imager. If you are in place, you can hide behind a karemat. "A polypropylene mat with foil will create an additional obstacle to detect your heat, and accordingly - protection from thermal imagers of enemy observers and snipers." It is also advised to erect at the shelter positions from the thermal imager in the form of a shield. It is believed that a tightly knocked down wooden shield of sufficient size, sheathed on the back with aluminum foil, will close the thermal circuit of the sentry or observer. But we must ensure that in sunny weather during the day this shield does not warm up in the sun, otherwise it will “glow” at night. Conventional glass hides well from observation in the thermal imager, better - a double-glazed window. At the same time, so that the shield or sheet of glass does not appear in the thermal imager as a dark spot of the correct geometry, it is necessary to fix the imitation of vegetation on their surface

    A good result is given by a fireproof suit that firemen use to work in the high temperature zone. He covers his face, arms, legs, but in him a person loses mobility.
    By the way, on the basis of refractory suits, they are now trying to produce special camouflage wraps, however, again - there is no one hundred percent guarantee, there is only a decrease in visibility.
    In nightly clashes, the weapon barrels will “shine” brightly and for a long time after the first shot, unmasking the position of the shooter. And a cigarette, even if you hide it in the palm of your hand or sleeve, will be practically a “spotlight” in the thermal imager, which will brightly illuminate the target for the sniper. In this case, in addition to disguise, it is advised to use the method of misleading the enemy with false thermal objects. Metal cans or boxes with heat from a fire or a lit candle, placed in front of the position in the direction of observation, will be bright spots for about a day on the screen of the enemy's thermal imager. Against this background, it will be more difficult to track an observer disguised as one of the above methods. And among many false targets, a heated barrel of an assault rifle will simply be one of the bright spots, among many. Experienced military personnel are also advised to check the effectiveness of anti-thermal imaging measures using their own equipment. And to do this at different times of the day, in various places, if possible - with different devices. Thus, in order to understand what the enemy can see in order to avoid fatal errors.
    Well, it’s impossible to drag a suit with circulating cooling under the natural background. Blocking someone else’s thermal imager is also complicated ... yet passive forms of struggle

    The fact that heat-reflecting and thermal-refracting materials are listed is good and interesting. But somehow the contact heating factor was not taken into account at all. Will explain:
    If you put on a padded jacket, then due to the high density and thickness of the layer, heat will not come out. But only the first 10-15 minutes, the heat does not disappear anywhere. Every minute, it heats the clothes more and more strongly from the inside. And after a certain time, ANY clothes become visible due to the heated surface. Even in some old issue of "Legend Destroyers" there was a dedicated issue to it. They showed that even a fireman’s suit will sooner or later release heat or heat up a little. But in the same place, they showed that glass is an ideal barrier to infrared radiation. But you will not carry it with you. Therefore, it would be better to discuss the topic of BARRIERS, like the camouflage shields / barriers that were used in the Soviet army. But only new panels will not visually close surface areas, but thermally.
    And I have not yet mentioned altitude observation. You can close shields and false targets from a soldier’s or tank’s thermal imager. But how to close the top of the UAV, helicopter and aircraft? Cover (at least pointwise) with huge canvases of polyethylene, it will be more difficult. After all, rising streams of air "flow" upward through the edges. To strengthen important communications, it is necessary to consider a heat removal system. The first thing that came to mind. This is to conduct insulated cables into the groove where water flows, which is washed into the river / lake. And then the large cable will not be visible, because the heat passes into the water, which will not leak anywhere and stagnate heat accordingly.
    I will be glad if you point out the errors)

        but what about people on the surface?

        Depends on the resolution of the thermal imager. Both in pixels and degrees Celsius. Because it is necessary to simulate the environment with sufficient accuracy. This raises a rather complicated problem. What in the optical range seems variegated and heterogeneous through a thermal imager can look completely homogeneous. At the same time, any small nonsense against this background will shine like a beacon only because the temperature of this nonsense is only 0,2 degrees higher or some material is not the same. This should be done with camouflage, which will fake a thermal drawing of the area. The only thing that comes to mind is to "prepare the canvas" first, i.e. equalize the temperature slightly below the average for the district. With the help of some heat accumulator or evaporator. And then apply “paints” to this surface using small heating elements. But this is for a stationary object. How to mask a moving object is pretty hard to imagine. Is that simulate transparency. A thermal imager will hang on the back and take a picture. And on the chest, the heated electronics will recreate this picture. If synchronized with movement, then you can try to take advantage of the low resolution of thermal imagers of the enemy, which will not allow them to see the flaws of the resulting picture.

          I think that at the modern technical level this problem has no solution. All the options we are considering are half measures. Otherwise, for a long time, something would have been known about effective means of camouflage ... How to achieve equalization of a person’s temperature “from the outside” with respect to the temperature of the surrounding air? Either to cool, or to heat, the third is not given. What to do with condensate? How not to overheat or overcool a person, how to remove excess heat and moisture from him? What is acceptable for space is categorically not acceptable on earth ... I am inclined to a multi-layer "spacesuit" with forced circulation of outside air under the upper layer.

            More precisely, at the present level of consciousness, the problem is not solved. In a practical sense, everyone understands that engineers can only heat conductors, but they can’t cool. That is, there are no circuits with a simple and direct effect on the same Faraday cage, so that the conductor can both be cooled and heated, or rather regulated in the necessary parameters. Hence the problem. If someone understood me.
