UAV signal recognition technology

Abstract

The wide application of drones brings convenience to all aspects of society, but also seriously threatens the safety of the low-altitude field. In recent years, the number of accidents caused by UAVs is increasing, and it is urgent to study effective signal recognition technology for UAV targets in the low-altitude field. Therefore, this paper introduces the categories of UAV signals and explains the basic principles of signal recognition technology. Then it concludes a variety of signal recognition technologies and compares and analyzes the performance of existing technologies. Finally, it summarizes and prospects for the UAV signal recognition technology.
