Abstract：Aiming at the problem of personnel target detection in cabin,a detection scheme based on millimeter wave radar is proposed.Firstly,the two-dimensional OS-CFAR algorithm is used to extract the target signal from the echo signal.According to the distance,speed and Angle information of the target signal,the point cloud data that can be converted into Cartesian coordinate system is generated and transmitted to the computer for processing.In the computer,the DBSCAN algorithm is used to cluster the different target point clouds in the point cloud data and the target count is completed according to the number of clusters.The experi-ment uses the AWR1642EVM module of TI company to complete data acquisition and preliminary data processing,and uses Matlab to design the host computer and display the clustering results and the number of people.According to the experimental results,it can be seen that the 77 GHz millimeter wave radar can complete the personnel target detection in the cabin.
