Anti-UAV System / Technology Development Trend Analysis

New anti-UAV technologies are emerging, such as intelligent responsive interference technology, multi-spectral threat perception and attack capabilities. It can be seen from the above development status that the development trend of anti-UAV systems/technology is:

1) Anti-UAV directed energy weapon

In the “black darts” test, a laser weapon system with a power of 30 kW was attached to the side of the “Ponce” dock-type amphibious transport ship, and a “gangster” drone was shot down. This proves that laser weapon systems can be used to deal with drones and other threats. The US Department of Defense is advancing several tactical laser weapons programs designed to use it against drones, shells, rockets and missiles. The high-energy laser project is developing tactical lasers with powers exceeding 100 kW.

According to reports, India will soon be able to develop a military laser with a power of 10kW to deal with drones and unmanned equipment. A few days ago, India conducted a 10kW laser test at the Hyderabad test site, destroying targets within 800M. Portable weapons for combating drones and light armored vehicles are expected to be developed on the basis of such lasers. In April 2016, the US Army demonstrated the capabilities of laser weapon anti-UAV.

2) Anti-UAV missile

QInetIQ and Sula Systems’ COUGAR (Anti-UAV Land-based Air Defense Additional Modular Requirements) research project, to develop a kinetic energy weapon, can be complementary to modern supersonic missiles in future land-based air defense systems. The low-cost, non-cooling long-wave infrared seeker searches for and identifies the target, and then directs the missile to hit the target. Although the interceptor missile is relatively small, 1.2M in length, 1.1M in wingspan, and less than 14kG in mass, it is close enough to the target to be subjected to severe structural damage, giving an obvious hard kill. With no warheads, fuzes and insurance systems, the cost of missiles can be reduced to $45,000.

In the “black darts” test, Boeing’s 1 AH-64 “Apache” attack helicopter shot down a “gangster” with an AGM-114 “Hailfa” missile with a proximity fuze. ) Drone. The “Gangster” is a civilian drone with a wingspan of 4.1M. Raytheon developed the FIM-92 StInGeR shoulder-launched surface-to-air missile to counter the current drone threat.

3) Anti-UAV defense system

Israel’s Rafael’s “Iron” anti-missile system in 2015 verified the ability to intercept drones. The ability to act as a super-short-range air defense system was demonstrated by testing the “iron shovel”, which used its radar to detect and track manned and drone targets. The system’s TaMIR interceptor continuously intercepts high altitude and low altitude targets by direct collision killing. System designer Rafael said that the highlight of the recent series of tests was the interception of multiple drone targets. The SPyDeR air defense system developed by Raphael is a point/area air defense system that uses the “PythOn” short-range air-to-air missile developed by Raphael and the DeRBy over-the-horizon air-to-air missile. Can also deal with drones.

4) Communication link / GPS navigation signal interference

The implementation of electronic interference against the operating frequency and wavelength of enemy UAV electronic devices will greatly limit its use in complex environments, and its on-board detection equipment and data transmission and processing will be affected or even fail. In order to achieve the purpose of cutting off the enemy’s information and intelligence chain, destroying or even commanding and coordinating it. Israel’s Rafael’s “UAV” anti-UAV system can interfere with GNSS signals, making it impossible for the drone to know its location and thus cannot return to the take-off location after losing control.

5) Anti-UAV radar

According to a reference report on April 25, 2016, Russia has developed a new type of panoramic surveillance radar that can be used to intercept drones. The system includes an “outpost” panoramic radar station and a “fly-1” optoelectronic component that can detect ground, water and low-altitude targets within 20kM.

The 2015 Black Darts test puts more emphasis on smaller UAVs, known as the Low Slow Small UAV (LSSUAS), which is less than 9kG and less than 185kM. /h, drones flying below 4570M. The “black darts” test shows that the most promising anti-UAV method is to use a combined system, that is, a warning network composed of radar, photoelectric sensors, infrared sensors, acoustic sensors and other detectors. The “black darts” test not only tested guns, guns, missiles and lasers, but also tested high-power microwave devices as well as GPS and radio jamming devices. However, it is necessary to find out in time to shoot down small drones, and it is more difficult to deal with groups of drones. The US Marine Corps develops a low-cost robotic group to combat unmanned aerial vehicle attacks. South Korea is studying the use of new technologies for acoustic anti-UAV. Resonance testing has been performed on a gyroscope, a key component of the drone, and an error message is output, causing the drone to fall.
