A Millimeter-Wave MIMO Radar Moving Target Detection Method Based on The Vehicle Platform

This paper proposed a signal processing method based on STAP (Space-Time Adaptive Processing), which uses millimeter-wave MIMO (Multiple-Input Multiple-Output) radar to detect moving targets under moving platforms.First, the received signal is converted into distance-Doppler data by basic signal processing, and then the scattering center is compensated by the velocity detected by CFAR (Constant False Alarm Rate Detector), and the compensated scattering center velocity is compared with the platform motion velocity to determine whether it is a moving target. The algorithm is able to extract the position and velocity information of the moving target with limited radar performance. Experiments show that the method can effectively eliminate the interference of stationary targets and ground clutter, thus achieving the detection of moving targets.
