In this paper,an interferometer is designed to be mounted on the UAV platform,and an interferometer direction finding method based on the improved least square method is adopted to achieve faster direction finding for the signal radiation source of the ground remote control.In addition,aiming at the direction finding error caused by the vibration of the UAV motor,an average filtering method is proposed to reduce the influence of the motor jitter on the direction finding accuracy.The simulation results show that the improved interferometer direction finding method can effectively improve the speed of direction finding while ensuring the accuracy of direction finding,and can reduce the direction finding error caused by the vibration of UAV.
