Abstract: A radar ranging method and a ranging radar are applied to an unmanned aerial vehicle. A first range to an obstacle is obtained using a first radar waveform. range. A second range to the obstacle are obtained using a second radar waveform if the first range is less than a preset switching threshold. the maximum detection range of the first radar waveform is greater than that of the second radar waveform; and a detection range resolution of the second radar waveform is higher than that of the first radar waveform.
