Abstract
The present disclosure provides a UAV control method. The method includes controlling an antenna device of a microwave radar of the UAV to transmit a microwave transmission signal and obtain a received signal, the microwave transmission signal and the received signal both being trapezoidal modulation waveforms, and one cycle of the trapezoidal modulation waveform including a frequency rising part, a frequency falling part, and a fixed frequency part; obtaining an intermediate frequency signal mixed by a frequency of the microwave transmission signal and the received signal to the radar controller, and determining whether the received signal is an interference signal based on the intermediate frequency signal; determining coordinate information of a detection target corresponding to the received signal if the received signal is not the interference signal; and updating a trajectory of the UAV based on the coordinate information of the detection target.
