[0031] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.
[0032] like figure 1 As shown in the flowchart of the vehicle classification method based on FM continuous wave radar according to a specific embodiment of the present invention, firstly, the constant false alarm rate processing is performed to estimate the power spectrum of noise and interference and set the threshold, and then the power spectrum of the vehicle is estimated. Peak statistics. After the vehicle's power spectrum peaks are accumulated to a certain number, a histogram of the results is performed. Finally, according to the results of the histogram statistics, the power spectrum peak energy segmentation thresholds corresponding to different vehicle models are adaptively obtained, and finally the purpose of traffic statistics and vehicle classification is achieved.
