Fire Detection System "SOVA"

Today, the prospects for the development of acoustic systems for detecting firearms are the most modern. Weapon constantly improving, but one thing remains unchanged - the shock wave from the production of a shot and the flight of a bullet.

So by calculating the known parameters, the shock wave can accurately determine the place of the shot. Since the shock wave of the bullet flight has a cone-shaped propagation, the top of which will be a flying bullet, the axis of the cone will be the trajectory of this munition.

Other characteristics are known:
- the angle of the cone depends on the speed of the bullet, which loses energy on the 1 XnUMX joule;
- the acoustic munitions flight level is approximately equal to 100dB
- sound wavelength 0.16-0.6 meter;
- approximate frequency range from 0.6 to 2 kHz.

As a result, if the system will use these mathematical parameters for counting and calculate them automatically, it will quickly determine the location of the shot.

When conducting reconciliation and peace enforcement operations, Western countries increasingly value the acoustic fire detection systems.
The United States has already successfully used such systems as PDC, Boomerang, Lifequard. England uses the BDI system.

The well-known French company offers a system for defining snipers "METRAVIB". Russian designers do not lag behind the French either. FSUE RFNC-VNIIEF offered the Russian military a system for identifying SOVA snipers, which stands for an acoustic shot detection system. This complex has the ability to determine the location of sniper shooters in real time. "SOVA" is made on 100 percent of the parts of domestic production and has passed all sorts of tests in all weather and time conditions. “SOVA” even managed to take part in military operations in the North Caucasus.

There, the system was used to guard the roadblocks, some points of deployment of various units and provide security guard groups.
It was the combat use that fully confirmed the highest indicators of the SOVA system. The system easily mates with automatic combat means of neutralizing firing positions, for example, the interface with the AGS-17 grenade launcher was successfully tested. Such a comprehensive solution ensures maximum minimization of the maintenance of the systems for determining and suppressing enemy firing positions.

Information arrives to the operator instantly, so coordinating the system is reduced to choosing priorities for the target. “SOVA” can facilitate the tasks of the scouts, as it easily defines targets with intensive firing to the 1 kilometer. It is possible to use the system to coordinate the fire of a separate unit using data obtained from various sources on the system. The system quickly makes calculations and provides real-time adjustment to the unit. Today, this system is supplied to the special troops of the anti-terror of the Russian Federation.

The composition of the system.

“SOVA” consists of special sensors for acoustic reception and a powerful computer. The main node of the system can be called a specialized software solution, which performs all calculations based on information from acoustic sensors. The task of the sensors is to constantly transmit information to the computer from all sides. The software cuts off any sound interference and processes only information relating to the production of a shot and the flight of an ammunition. All information processing comes down to the following: first, the sensors transmit all the information collected from the surrounding space to the computer. Then, on a computer, the software solution calculates the parameters of the acoustic wave, on its basis, calculates the trajectory of the passage of the munition and, using this data, gives as a result the clear coordinates of the place from which the shot was fired.

The main characteristics of the SOVA system:

- the number of driven targets is not more than ten units;
- sector detection target 360 degrees;
- the maximum caliber of driven targets to 14.5 mm;
- the determination error to 500 meters is equal to 5 percent;
- the determination error over 500 meters is equal to 10 percent;
- spacing in azimuth does not exceed one percent;
- identification of small-caliber targets up to 0.6 kilometers;
- definition of large-caliber targets to 1.5 kilometers.

The ideas of our defense industry are brilliant and simple. But what a wretched performance .. - the remote control seemed to be cut down with an ax.

[Phoenixl]

Amers have the same
A couple of years ago they showed on the discovery

[vadimus]

The main thing is simplicity and reliability. Yudashkin, after all, is transformed to design. Enough, the form is already stuck enough for the army

[bober]

Yes, there are none ... I just peeped at the Americans and how to say that we also do not. So the dummy is just

[Artemka]

And what kind of fur balls on the first photo are the sensors or what?

[Andrey77]

Microphone protection. Aren't you surprised by the "knob" during a rock concert? You can make and not "balls" for esthetes. ;)

[Dimka off]

great system. Now the main thing is to begin large deliveries to your army.

[PSih2097]

They won’t join the army, they’ll be more useful to cops ...

[J_silver]

You want to say that from one point you can determine the coordinates of the target? This cannot be in principle ...

[Passing]

There are seven microphones, the distance between them by eye is 30 cm, the length of the sound wave from a typical bullet is 60 cm maximum, i.e. and there are no contradictions with Kotelnikov’s theorem, then I think it’s clear ...

[PSih2097]

why coordinates, direction and removal ... as a rule this is enough.

The azimuth and range are the coordinates of the target, or rather one of the types of coordinates. If the machine is equipped with a GLONASS receiver, then it can immediately translate the received coordinates into geographical coordinates.

[Boot under the carpet]

Large supplies of this device to the army are illogical! If they do, then only in small-scale production to equip the troops in hot spots. For example, the "Arena-E" complex is needed on a large scale, especially for tanks with "flying towers", but I have not heard about their delivery either.

[Fireman]

This is a complete deception, Russians 10 years ago in these technologies!

[PSih2097]

There was a discovery program in my opinion, there a former Silovian tried this kind of thing ... only on a humvee basis ... my opinion is against the partisans ...

[Passing]

In my opinion, in this form, this system is not effective.
Just imagine a conditional situation - the car began to be fired from an ambush. There are two development options: we press on the gases and break through from ambush at speed, or press on the brake, the fighters from the car into the loose and begin to crush the enemy firing point.
And how will SOVA help in this situation?
In the first case, it will not affect at all, there will be no time.
And in the second, IMHO, it will only interfere:
While the operator in the car will visually compare the marker on the indicator with the terrain, while he will visually measure the distance of 328 meters from the bulldozer, and look for exactly where the shooter is hiding, while the operator shouts to the rest of the fighters (who have fled along the side of the road) and confusedly explain to them, that de "shoot that bush tenth from the right, which is thirty meters to the left of that tree, but which is not an aspen, but which is an oak, but not a small oak, but another, which has branches in!". In addition, an operator under fire will be oh, how dumb it is to understand this trigonometry - while he is here engaged in highly intellectual exercises, a godfather from the same bushes will fly in, and ...
In short, long and dreary. And most importantly there is no special meaning, it is much easier to find the enemy in the old fashioned way, with eyes and ears.

IMHO, in order to have real benefits from such a system, you need to digitize the output of this device, i.e. so that the three-dimensional coordinates of the shooter and the type of weapon used are issued. And it is highly desirable to increase accuracy in direction. What will it give?
1) There will be an opportunity to tie this system to the "unified tactical control system", ie. each soldier, on the digital map of his handheld, will automatically have marks of enemies and the type of weapon used by him. It is clear that you still have to look with your eyes, but in general the process will be incomparably more effective. In addition, it is immediately clear that this shit, with a small one, we will beat last, but this ghoul, with a large-caliber sniper, must be extinguished immediately ...
2) If accuracy is significantly improved, it will be possible to automatically bombard enemy points with the help of remotely controlled modules, this will be a beauty at all, we don’t even have to stop at every bombardment, we just set up a grenade launcher for an automatic response, and slowly, demonstratively, drive along roads chosen by militants ...

[Justme]

Why minus a person and his point of view - the opinion is quite logical - the system looks a little damp and there is still something to complement and refine

[sedoj]

The first part is a joke, the second is not without meaning.

[almost demobil]

You say it is not effective, then right there, point 2) admire how cool it is. There is no problem, selsyn drive to the turret and you can stupidly smoke. Useful thing.

[Passing]

The devil, as you know, is hidden in "little things".
1) Selsyn drives? Sure sure. If it could be done cheaply and cheerfully, then of course, but alas, it’s practically impossible to implement effective weapon control systems on analog feedback positioning devices in a compact, reliable and cheap form (all at the same time). This is not my opinion, but a historical fact - such control systems were used only in large and expensive military vehicles - for example, in the LMS of tanks and anti-aircraft artillery like Shilka. And what was easier equipped with control systems with mechanical connections. And what's the point of putting this complex, bulky, capricious, expensive system on every armored vehicle or, say, MRI, when the introduction of digital electric drives and computer control systems is in full swing, which are much more compact, more accurate, more reliable, and ultimately cheaper, and what’s the most most importantly, which integrate perfectly into automated control systems?
2) The accuracy of this system is 5% of range, which is clearly not enough. For example, Kalash accuracy is 0,1-0,2% of range. Those. at one hundred meters, the accuracy of determining the coordinates is 5 meters, at 200 meters - 10 meters, etc., plus the accuracy of the guidance system and the error of the weapon itself. Those. the ability to use a machine gun immediately and unconditionally is excluded, the easel grenade launcher remains when firing at a range of up to about 100 dead, and the defeat of the enemy will not be guaranteed. In general, without a serious refinement of accuracy, a prodigy does not work.

This system is designed for other situations.
The checkpoint, on it an armored personnel carrier with such a system, the fighter is on guard duty. BOOM, shot. The system gives the approximate location of the sniper, then either mortars or "KORD" with a thermal imager are turned on.

Quote: Passing by

while the operator screams to the rest of the fighters

Target designation can be done either with a tracer or with a smoke grenade.
I would also like to note the psychological effect. If the enemy is aware that this system is being used, then he will act more carefully and less efficiently.

Those. better without her? This is the first generation, to Glanas it is fully realistically tied.

Sound reconnaissance was first used in Russian artillery .... Five years after the end of the Russo-Japanese War, an officer of the Russian army, Captain N. Benoit, constructed the first sample of a sound-measuring station, the work of which was based on the "time difference" method. I note that this type of reconnaissance appeared in the French and German armies in 1915, in the British - in 1916, in the American - in 1917 ... The first notch of enemy firing batteries was performed in August 1914, and the first firing service was in November of the same year. So the priority of using the phenomenon of sound propagation in the atmosphere, arising from shots, belongs to Russia ... "Sova" uses the same method of "time difference" of sound arrival to microphones located at a certain distance from each other. And then - "naked trigonometry", solved on a slide rule, as it was before, or a computer as it is now ...

Yes, I ask how much bought in the troops. I wanted

[Simonov]

You don’t need to press F1 - and so everything is clear.
Iron - NATO boomerang, taken from the Georgians in the 888 war. Software was written by two birdies for 4 kopecks and a chupachups.
The interface is made on Windows, not only in combat conditions, in ordinary hangs and glitches. If you develop it yourself - the software is written in assembler, or to the extreme on embeddedlinux. The electronic compass is assembled on the knee, a prototype is immediately visible. Three firing points are visible in the photo. According to the calculated trajectories (blue lines) it can be seen that they fired not aiming, but like fanning in white light like a pretty penny. Campaign instance is the only and demonstration. They are unlikely to go into the series - there are no source codes for software for hardware.
Okotono hear objections

[Honory]

In any case, the thing is useful. Better with it than without it. For example, at night.
