The US Army called the required characteristics of the "friend or foe" system for infantry

The U.S. Armed Forces turned to industry with the question of the possibility of creating special sensors that could increase the level of combat security in the unit in the dark. These sensors should help infantrymen identify their fighters in low visibility conditions.

In circulation, the system is denoted by the acronym IFF (Identification Friend or Foe). This is a friend-or-foe system for army units.



Basic requirements for the sensor: light weight, low power consumption, high stealth, a high degree of authentication by soldiers of their army, integration with military uniform kits. The system can be initially built into the individual equipment of an American soldier, not to unmask it.

The maximum area is also indicated - up to 9 square meters. inches (up to about 58 sq cm). The detection detection distance is 300 m.

It is assumed that the sensor should be located either on the fighter’s protective helmet, or on the upper part of his body (clothing).

From the requirements:

It should provide at least 270 degrees of the detected coverage area.

An important detail is added: the sensor should minimize detection by conventional night vision optics.

Some prototypes have already been created in the United States, but so far, many claims have been made against them by the military themselves. The new IFFs should help the fighters identify themselves at the battlefield in order to avoid the so-called “friendly fire”.

      weird guys. They have a system for determining "friend or foe" for airplanes through a stump-deck works, and they already climb to people.

        And how will this system work when the enemy uses electronic warfare? And it will turn out: "At night all wolves are gray"! Yes

          When did the Americans fight with technologically advanced countries? Again, this know-how is designed for different barmaley. But only until the moment when it becomes known to be beaten ... and then there are craftsmen))))

          Fair question.
          I think we will only have to wait for the development of quantum technologies (they just don't care about any means of electronic warfare: because they track pairs of "entangled" - entangled - particles, which lose their entanglement when observing them). But if it ever will be (enormous resources will be required - and this is not about money), then not earlier than the last quarter of the XNUMXst century, as it seems to me.

        Everything is normal. Ultimately, they will switch to the system: who are you? - yours, and you - "cuckoo".

        I don’t know about airplanes. But the Georgian-Ossetian conflict, as far as I heard, their land-based state recognition systems showed themselves better than Russian ones.

        Well, in fact, nothing surprising, tk. in the category "friendly fire" (uh ... "friendly fire ") the US Army has historically been ahead of the rest. By the way, on this subject, you can also file an article - I also guarantee rzhaka, I guarantee.
        So they are trying, sickly, to do something about it. And given that not so long ago they were allowed to join the service of all drug addicts and psychos - they are really required.

      Looks like the problem of "friendly fire" completely overcame. Although it was always and everywhere. The first time it became a real problem was during Napoleon's campaign against Russia, where everyone, the Austrians from the French, the Poles from the Prussians.

        The problem has always been. Even in the wars of antiquity.
        Therefore, the standard flags were so important. There were a lot of them. Without them
        in hand-to-hand battles chaos began.
        And the problem has not been resolved so far.
        And all modern armies are looking for solutions.

      Yes, they probably will not come up with anything worthwhile - they will either unmask, jam, or work normally only in the bare steppe, or they can easily be reproduced by the enemy, or prohibitively expensive. Although systems for limited use for special forces will undoubtedly appear. Ordinary infantry should be content with passwords and untranslatable ideomatic verbal constructions that are inaccessible to the enemy.

        The IDF tried several times to introduce such electronics
        in the infantry. And even checked in operations in Gaza. But sufficient
        reliability did not work. Sensors only seem to exist
        at the junior officer level. But not every soldier.

            Connected to a satellite network along with tanks, armored personnel carriers, helicopters.
            Now they have connected the F-35.
            It creates a real-time picture of how the army moves.
            IDF operations are always nightly. Clear business without headlights and lamps. And now
            and walkie-talkies try not to turn it on.
            All on night vision devices. And the network helps headquarters command.

              In the sense of ? Do they not use radio communication at all? Even through the ZAS with "packing" into a short signal? Is everything going through a satellite? This is how much data, most of which is pointlessly expensive for such a price. And what about tablets in equipment for network control - it will not always save you from "friendly fire", and you can also jam the network. Although each army is trying to equip itself according to the alleged enemy.

            On a passive oscillatory circuit. When you buy something in the supermarket, you can look at the "anti-theft label" there, this is the very outline. Only made disposable - burned by a strong magnet. And if it is made durable, then it does not consume anything at all, being excited when it is irradiated with a radio signal of a certain frequency. Under such irradiation, the circuit emits a response signal that allows it to be identified.
            With the help of some improvements, a fairly stable identification system can be made, about which there was an article about the next Israeli achievement. I think that the Pentagon’s tender is a consequence of the shock work of the Israeli lobby, which, naturally, wants to sit down on abundant US funding as usual.
            To say that such a system needs to be done via satellite ... Well, you need to keep the secrets of your country, confusing the enemy as much as you can! Hehe ...

              Such contours are "tuned" to a certain frequency and are easy to manufacture, and accordingly the enemy will be able to copy such marks. Accordingly, circuits with variable frequencies or, ideally, with pseudo-random switching are needed. These are already elements of the ZAS and are expensive to equip all fighters. In addition, with combined arms use, there will be difficulties in organizing the use and synchronization of such devices.

                Do you know that any circuit can be quickly rebuilt by turning one handle? Well, if you didn’t print it on a piece of paper, how is an anti-theft mark? Then he drove the fighters through the receiver, checked that everything was correctly rebuilt, and you have a completely different frequency, for today's exit. And tomorrow I rebuilt again. Combined arms tuning will be stupid, although you can adjust it, there are no fundamental difficulties at all.

                  make a device like a radio scanner and every day see what the enemy's "identifier" frequency is, accordingly rebuilding your "clones". Understand - I am not saying that such devices are not promising. They are unpromising in large volumes. For spetsnaz or intelligence, they are quite appropriate and promising

                    Well yes. Every weapon has its own weapon. No wunderwaffles, and apparently will not. Refreshing new thought! True, it was not voiced by you, it seems ... for the first time it sounded, as I understand it, at the military council of some Cro-Magnon tribe. And they also said that every weapon has its own niche of use. In this case, a friend or foe identifier is not needed at all throughout the army, this strange idea did not even occur to me until you for some reason expressed it.

      Well, what? The idea has long been in the air, so sooner or later a solution will be found.
      It remains to figure out how to avoid the so-called "friendly fire" at the hands of a badly-hanged, prickly twin-mortar mortar from a neighboring site.
