On July 30, 2017, in the third reading queue of the parade of the 90th anniversary of the founding of the People's Liberation Army - the fourth group of party members of the information-based combat group, the domestic new anti-radiation drone was first seen in the public Unveiled the mysterious veil. Although it is also a counter-radiation drone with Israel "Habi", the new type of anti-radiation drone made in China has surpassed the early "Habi" drone in terms of technology and performance.
the student surpasses the master
The so-called anti-radiation drone is a suicide attack drone used to deal with enemy radars, communication ground stations and other electronic radiation sources. Its attack mode is: autonomous flight after launch, enters the cruising altitude, and then travels for a long time in the target over the long-term area, using the sensors carried by itself to reconnaissance, monitor and lock the target, and lock the radio transmitted by the enemy radar. A dive attack is initiated after the signal to destroy the antenna or host portion of the target in a near vertical hit. Compared with anti-radiation missiles that mainly target targets such as radar stations, anti-radiation drones are cheaper, more cost-effective, and have longer standby time on the battlefield. They are more suitable for combating enemy stealth and mobile. Weapons of the radar facility.
China's anti-radiation drones began with the introduction of the famous "Habib" drones introduced from Israel at the beginning of this century. Chinese research and technical personnel developed and absorbed through the introduction and re-innovation of "Habi" related technologies. The first generation of domestic anti-radiation drones filled the gap in this field. Then, with the continuous improvement of China's drone technology, we continuously improved the design and development level of anti-radiation drones, and finally launched a new generation of anti-radiation drone products, which realized the "Habi" in terms of technical performance. Beyond. As early as the Abu Dhabi Defense Exhibition held at the beginning of this year, AVIC exhibited the foreign trade ASN-301 new anti-radiation drone developed by the Institute of Drones of Northwestern Polytechnical University. This time, the self-use model was also made public for the first time in the military parade.
Technical overview
In terms of appearance, the new anti-radiation UAV system adopts the design concept of the mobile launch system. It is powered by a high-mobility 6 & TImes; 6 military truck, carrying 6 integrated launch box systems, using two rows of three launch boxes. In the cloth mode, the launch box is slightly tilted upwards. In each integrated launch box, not only a new type of anti-radiation drone, but also other ancillary systems, including take-off ejection systems and guide rails, are placed. The drone launching system adopts a fully automatic mode, which can be issued by the control personnel in the mobile launch vehicle, or remotely transmitted via the radio command system.

The specific parameters of the domestic self-use type anti-radiation drone that has appeared on the military parade have not been announced yet, but according to the foreign trade ASN-301 anti-radiation drone, we can infer that the overall design of the machine is a small aspect ratio with no tail delta. Layout, the leading edge of the wing is thicker, and it should have better aerodynamic efficiency and lift in the subsonic speed range from the airfoil. The maneuvering airfoil includes a full-wing awning, a wing-tip rudder (ie, a winglet). The fuselage is cylindrical, the head is a sphere with a diameter larger than that of the fuselage, and the surface is optical glass, which has an enlarged radio detection and photoelectric equipment compartment, and the detection system of the drone is mostly placed here. The machine has a compact pneumatic control design, which is equipped with four folding direct side airfoil surfaces on the wing, so that it can realize the turning without tilting action during horizontal cruising and dive attack. We know that conventional pneumatically operated aircraft must be slippery when cornering, and side slip will cause a certain degree of deviation of the route and attitude. Without direct force turning with tilting action, the route deviation can be avoided, and the attack target can be significantly improved. The ultimate hit accuracy is maximized. Direct force turning is a very new aircraft control technology. The new type of anti-radiation drone will put it into use, which shows its high technical content.

Technical characteristics
First, the range of operations is long and the standby time is long. The new anti-radiation drone is propelled by a tail-push propeller engine with a life expectancy of more than 4 hours, a maximum cruising speed of 220 km/h, and a mission radius of over 280 km/h.
Second, the detection and sensor system is multi-functional, and the guidance system is more accurate and anti-interference ability, which greatly exceeds the “Habi†drone. In addition to the installation of the anti-radiation receiver system, the new anti-radiation drone has also added two guiding modes: photoelectric video reconnaissance and real-time image transmission. In this way, in addition to receiving the radar radiation source signal, the UAV can also The head-mounted optical video guidance system firmly locks the target of the enemy radar station. At this time, whether it is the bait radiation source interference or the conventional electronic countermeasures such as radar shutdown, the UAV is completely ineffective, which greatly enhances its resistance. Electronic interference capability and hit rate.
Third, it has better control of data link control and human control in the loop than the early "Habi".
Fourth, the new type of anti-radiation uses a high-performance anti-radiation radar seeker with extremely high tracking accuracy.
Conclusion
Earlier, there were reports from foreign media about the use and equipment of the People's Liberation Army troops to use anti-radiation drones, but they have not been confirmed by the official authority of China. The public display of the parade-type anti-radiation drones indicates that our military has determined that it has the mature technology and sufficient capabilities to equip and use such anti-radiation drones. It will pose a great threat to high-value targets such as enemy air defense weapon system radar systems and command systems.
