The invention discloses a model classification method based on a frequency modulation continuous wave radar, and belongs to the field of vehicle detection of intelligent traffic. According to the invention, first of all, constant false alarm rate processing is carried out, the power spectrums of noise and interference are estimated, thresholds are arranged, and then the power spectrum peak values of vehicles are counted; next, histogram statistics is performed on the counted power spectrum peak values of the vehicles; and finally, according to results of the histogram statistics, power spectrum peak value energy segmentation thresholds corresponding to different models are obtained, and the types of the vehicles are determined based on this. The method provided by the invention has the advantage that the different models can be classified by use of the frequency modulation continuous wave radar.
