With the development of unmanned aerial vehicle, the corresponding unmanned aerial vehicle countermeasure system has also developed in recent years. With the development of the unmanned aerial vehicle industry in recent years, more and more unmanned aerial vehicles are in possession. The size of unmanned aerial vehicles is small, very convenient, and easy to operate. More and more people have unmanned aerial vehicles. Most pilots do not have flight training, existing UAVs are highly intelligent, and an ordinary person can start in five minutes. These pilots without professional training fly in various situations, resulting in explosives, injuries, affecting flight safety, state secrets security, and so on. First, we need to understand the working principle of the UAV countermeasure system. For the countermeasure system of small and low-speed UAVs, first detect and then counteract. For detection, there are two types of technical systems, spectral detection and radar detection. Secondly, we should be clear about the selection of UAV anti-aircraft system, there are the following points:

Reasonable selection of detection mechanism

Based on the working principle, the object to be guarded against and the actual use of the field environment, the detection mechanism can basically make a reasonable choice, for example, our air defense target is a regular model similar to DJI. The area to guard against is a gym concert in the city, in which case it is sufficient to have several counterfeit guns.

Reasonable selection of detection distance and interference distance

Among the many basic parameters, one is called interference suppression distance, which in principle can be increased by increasing the transmission power. However, this may cause other problems most directly related to electromagnetic pollution.
