When there was a conflict between Azerbaijan and Armenia in Nagorny Karabakh region (referred to as “Naka region”) and there was the biggest military confrontation between the two sides since 1994, what the world saw was that both sides used UAVs and put them into the war at a deeper level. In particular, the Azerbaijani side has repeatedly dispatched drones to launch missiles against Armenian tanks and armored vehicles. The tank, known as “king of land war”, has become an iron coffin on the Naka battlefield. Azerbaijani’s use of “Halop” suicide drones to air attack Armenian s-300ps long-range surface to air missile positions and destroy a missile launch vehicle makes people feel breathtaking – after all, S-300 missiles are the main air defense system equipped by many countries.

The reason why Azerbaijan is able to use UAVs on a large scale is mainly because the modern combat system of its opponent, Armenian, is relatively weak and cannot counter the UAVs. In fact, for a military power, it not only has strong air defense and anti UAV capabilities, but also is constantly bringing forth new ones and developing new anti UAV technologies.

For example, the “acoustic detection array anti UAV system” being developed by northern China’s industry has its own characteristics, and is especially suitable for small and medium-sized countries with weak air defense capability. The characteristic of this technology is to set up several acoustic detection arrays on the ground. When the UAV enters the relevant airspace, the specific frequency noise generated by its propeller will be recognized by the acoustic detection array on the ground, and the position, altitude and heading of the UAV can be locked accordingly. After that, the radar and infrared detection system can be used for precise locking, and command the air defense firepower to destroy.

China develops anti UAV system of acoustic detection array, which uses radar and infrared detection system to lock in

In fact, the use of acoustic detection equipment to discover aircraft had been used before World War II. But at that time, it was a relatively backward air defense listening system, which could only be roughly judged by a number of listening devices, and then simply reported by telephone and telegram. Because the efficiency of this listening system was not high, after the emergence of radar, this kind of air defense listening device quickly withdrew from the stage of history. Now, the reason why the acoustic detection air defense system can come back is mainly due to the following factors. Firstly, the emergence of low slow small targets makes it difficult for traditional radar to play its role; secondly, the progress of modern technology. The effect of the acoustic array detection system based on computer automation is better, and it can connect the acoustic detection system of the whole theater or the whole country through optical fiber. As long as the enemy aircraft enters, it is difficult to escape tracking.

Another advantage of the acoustic array detection system is that it is always in a passive and silent state, and the enemy’s Anti Radiation Radar and various interception devices can’t be locked at all. Of course, there is no way to counterattack. This advantage is particularly suitable for relatively small and weak countries. Take the Asian Arab conflict as an example. If Armenian is equipped with this kind of acoustic detection system in advance, it will be able to form an effective early warning for the Arab UAV, and it will not fall into the situation where the air defense missile is knocked down by the UAV and has no response. Even if the other side interferes, the acoustic detection system can still work normally. It will not let the other UAV go into the uninhabited world and bombard its own ground equipment. From the war between Asia and Arab countries, it can be inferred that UAV technology and anti UAV technology are developing simultaneously, and we are in the forefront of these two points. Therefore, in the future battlefield, China can achieve both offensive and defensive, and also can achieve both ends in the arms market.

In a word, for UAV, a new battlefield form and “new spear”, its birth inevitably means that the “new shield” against it will also come out. After all, no one wants to be beaten

Shooter’s “killer” — gunshot detection system

The gun sound detection system is developed from the gun positioning technology. It can quickly find the shooter’s position according to the sound wave emitted by the bullet, so as to take countermeasures in time, so as to reduce battlefield casualties. In the battlefield of Iraq, terrorists with sniper guns have become one of the important threats to the US military. The US military is equipped with a large number of gunshot detection systems, which promotes the development and application of this technology. The gunshot detection system has gradually expanded from ground application to vehicle, individual equipment, gun and other occasions.

Vehicle borne gunshot detection system

The vehicle borne gunshot detection system is installed on Humvees, armored vehicles and other combat vehicles. It has 360 ° omni-directional situation sense ability, and can quickly locate and track the source of single shot, multiple shot and spot shot gunshot. Generally, the farthest detection distance is 1000m ~ 1500m, the azimuth accuracy range is ± 3 ° to ± 5 ° and the range accuracy is ± 20%. The main products are pdcue (projectile detection cueing) gunshot detection system developed by AAI company and boomerang series sniper detection system developed by BBN technology company. Among them, the boomerang system has been upgraded for many times by type I, type II and type III, and the cost is controlled within 10000 US dollars. It can be quickly installed within one hour, and the performance has been further improved. It takes less than 1 s from capturing the gunshot signal to completing the complex algorithm to calculate the direction of the bullet, the location and direction of the shooter.
