description The invention relates to a radar-based animal group respiratory rate detection method. The method comprises the following steps: acquiring a radar signal; performing distance dimension FFT and speed dimension FFT on the radar signal to obtain a distance dimension FFT result and a speed dimension FFT result; respectively carrying out distance dimension constant false alarm detection and speed dimension constant false alarm detection on the distance dimension FFT result and the speed dimension FFT result to obtain a detection target set and detection target set data; extracting the phase of each detection target in the detection target set; and according to the phase of the detection target, calculating the respiratory frequency of the corresponding detection target. According to the technical scheme, the speed dimension FFT is carried out on the ADC data of the radar signal used for detecting the respiratory rate of the animal group, the moving animal can be recognized through the speed dimension, the moving t
