Recently, a "world's largest petroleum processing facility" and an oil field attacked by Saudi Arabia's Amy Oil Company have seriously affected Saudi oil production. The armed forces subsequently declared "responsible for the incident" and declared that they had attacked 10 of the uavs. Due to the large number of UAVs that may be involved in the attack, analysis has linked the attack to the "UAV Buzzer Warfare". So, is this attack really a drone swarm attack, and how much threat does this attack pose? How to deal with such attacks?
Experts say that in recent years, the success of UAV attack should be called "surprise attack". The success of the attack is also due to surprise. In fact, many countries have developed perfect UAV detection, tracking and interception countermeasure systems. If a better defense system is deployed in advance, at least it will not cause so much damage.
The first problem in disposing of such UAVs is to solve the problem of difficult discovery. In addition to continuously improving radar performance and increasing temporary deployment points, it can also assist detection through a variety of means. The first is the infrared search and tracking system, which is very mature and widely used in air and ground detection. Because of its small size and no external electromagnetic radiation, it is suitable for locating small targets near the city's main points. In addition to the common detection methods mentioned above, UAV can also be detected by radio environment monitoring. once the UAV control signal is found, the early warning can be issued, and the control source and the UAV sending radio signals can be positioned. In this way, the combination of active detection and passive monitoring can ensure a high detection probability for small civil UAVs around key targets.
We have passed the detection barrier and the interception barrier. The most direct way is "hard killing". Some anti-aircraft artillery and missiles can be intercepted at greater distances. The base of the Russian army was attacked by a small UAV for many times, and most UAVs were shot down by Russian armour missile and air defense system. Of course, in downtown areas, the collateral damage caused by anti-aircraft guns and missiles may be greater than that caused by small UAVs. This has led to the emergence of a new means of hard killing - lasers. At present, the anti UAV laser almost shows the trend of letting flowers bloom.
Even in the absence of effective physical killing, or even in the absence of unmanned aerial vehicles, small unmanned aerial vehicles can be driven away or forced to land by means of "soft killing". At present, civil consumer UAVs mainly use GPS and other satellite navigation and positioning systems to implement positioning and navigation. If their navigation channels are blocked, these UAVs may become "headless flies". In the vicinity of important targets, the unmanned aerial vehicle (UAV) may be driven away or forced to land by GPS jamming, which makes it impossible for UAV to receive navigation signals. Russia and its surrounding areas even use GPS spoofing technology to updat the GPS signal near the area into signals from another area, so that the civilian UAV "halo", even if it enters the relevant areas, it can not find the real target. In addition to suppressing the GPS signal, it can also interfere with the UAV control link, make the UAV out of control, or obtain its control rights, and then forced landing and driving out of the UAV.
