Radar signal processing method and device and aircraft

The invention discloses a radar signal processing method and device and an unmanned aerial vehicle. The method comprises the following steps: controlling a radar of an aircraft to alternately send electromagnetic waves according to a constant frequency and a non-constant frequency; acquiring a plurality of first echo signals from the echo signals corresponding to the electromagnetic waves, wherein the plurality of first echo signals comprise signals reflected by the electromagnetic waves with non-constant frequency and emitted by the radar when meeting an obstacle; and processing the plurality of first echo signals. According to the invention, the technical problem that the radar cannot accurately identify the object due to the interference of the propeller of the unmanned aerial vehicle to the object detection is solved. 本申请公开了一种雷达信号的处理方法及装置、无人机。其中，该方法包括：控制飞行器的雷达按照恒定频率和非恒定频率交替发送电磁波；从电磁波对应的回波信号中获取多个第一回波信号，多个第一回波信号中包括雷达发射的非恒定频率的电磁波遇到障碍物反射回来的信号；对多个第一回波信号进行处理。本申请解决了由于无人机的螺旋桨对物体探测造成的干扰造成的使雷达无法准确的识别物体的技术问题。
