With the rapid development of UAV industry and the wide application of UAV in all walks of life. For the coming "black flight" UAV problem, the government is also constantly promoting various countermeasures and defense measures to ensure the stability of social order and the safety of airport routes, and will not be threatened and confused by "black flight". Nowadays, UAV anti-aircraft technology is well known by more people, and its application fields are also very wide. For example, there are often illegal intruders in airports, gas stations, nuclear power plants, petrochemical plants, detention centers and other fields. Through the use of UAV countermeasures, after monitoring the abnormal UAV, determine whether it is "black flying" according to the actual flight situation of the UAV, so as to implement the countermeasures against the UAV and achieve the expected effect of defense.

The development of UAV reaction technology paves the way for solving the situation of UAV adverse phenomena, focuses on the development and transformation of UAV technical characteristics, application concepts and methods, continuously increases the range of practical activities, looks for practical solutions, better responds to various UAV problems in the future, and continuously updates UAV reaction measures.
