In the United States, more and more drones are being put into use, and they are used in various fields to support individuals and companies in accomplishing tasks. For example, the stadium will shoot the game in real time, the wedding scene will be broadcast live on the wedding, and the farmers will use the drone to verify the harvest.
In the government's public sector, they use drones to rescue disaster-stricken areas, respond to accidents, broadcast live broadcasts, etc. It is estimated that the United States currently has 1.2 million to 1.8 million drones in use, and their number is very high. It is difficult to estimate, thus causing a series of problems for the government authorities.
Airborne drone detection is one of the major problems encountered at present. On the one hand, the UAV is too small, and on the other hand, it is difficult to detect it by its high speed. If the drone is not recognized, it is difficult to take any countermeasures against the drone in flight.
There are several ways to capture drones in the field of expertise: using the latest technology from different fields to track and even capture drones, as well as recording sounds and saving them in a database for later detection of drones. The other is recorded by the radar system, but the wrong drone is easily confused with birds, so the small drone is difficult to distinguish by the radar system.
With the generalization and profitability of drones, the use of drones has also brought a lot of negative effects. For example, in the prison, the unloading of drugs and weapons, the remote control of drones to throw bombs, and even the usual drones in life to steal and steal other people's information, so anti-UAV becomes very urgent.
So how do we prevent drones in reality? The most common use is to use UAV jammer to shoot down drones, force drones to land or return flights, such as large conference centers, opera houses, etc. Currently, the UAVs on the market are mainly common WiFi 2.4G 5.8G bands. When the UAV jammers equipment works, it only affects the UAV and will not affect other frequency bands, thus not affecting the normal operation of other electronic equipment on the site.
