In recent years, different types of drones have appeared frequently. The price of drones is becoming more and more humane, and the "threshold" for operating drones is getting lower and lower. The structure of the UAV itself is simple, and the consequences of carrying appropriate weapons can be imagined. Many terrorists, criminals and other dangerous persons may use drones mixed with various weapons, posing a huge threat to the security of all countries. Therefore, the birth of drone countermeasure equipment has become the first choice for the development of military industry and commerce in various countries. Considering the continuous development of drone technology, drone jammers have continuously adopted strict confidentiality measures to prevent information leakage. However, this can still be learned in some other way. Depending on the type, current UAV GPS Jammer interfere with UAVs by detecting, tracking and intercepting them.

In the military field, drone jammers can be used to prevent enemy drones from reconnaissance and attacking military targets. UAV jammers can emit electromagnetic interference signals that interfere with the control and communication signals of enemy drones, causing them to lose control or reduce accuracy.

In the field of public safety, drone jammers can be used to prevent unauthorized drones from entering sensitive areas, such as airports, nuclear power plants, government agencies and critical facilities. The drone jammer can force the drone to lose control or return by interfering with the communication signal and navigation signal of the drone.

In the commercial field, drone jammers can be used to protect confidential information and intellectual property of commercial organizations. For example, some companies could use drone jammers to protect their research labs or production facilities from drones.

Some drone jammers use radar, optics, infrared cameras, radio reconnaissance and other detection methods to find the drone in the target. Since it is difficult to find UAVs in complex environments by single detection and tracking, sensor fusion has become a new direction for the development of UAV jammers. After locating the target, enter the equipment interception stage. Interception methods include radio signal jamming, laser strikes, and a combination of other means.

Interfering with drone communications is one of many ways drone jammer can do it. By jamming the UAV signal, the communication equipment of the UAV is affected, and a series of failures may occur. Traditional means of jamming UAVs also include air and ground signal strikes or jamming. Many drones fly slowly. Once such an incoming drone is found, it can be detected by drone countermeasures for strikes. In addition, technologies such as drone countermeasures that perform missions through higher-level systems continue to develop.
