In order to improve the communication reliability of unmanned aerial vehicles under complex electromagneticenvironment conditions, based on the communication system of unmanned aerial vehicles, a communication interference perceptionmethod based on electronic warfare features is studied. The method perceives the electromagnetic characteristics of the environmentand interference signal characteristics, intelligently makes decisions based on the interference recognition results to automaticallyavoid interference, and conducts data communication on the optimal channel, it can significantly improve the anti-interferencetransmission capability of unmanned aerial vehicle communication systems in complex electromagnetic environments. And constructa prototype of interference perception and automatic avoidance testing and verification principles, conduct field testing andverification, achieve intelligent adaptation of drones (swarms) to clutter environments, and meet the growing demand for droneapplications.
