The application discloses a millimeter wave radar point cloud enhancement method for trajectory smoothness evaluation and occlusion compensation, and belongs to the technical field of radar signal processing. The method performs clustering and inter-frame association on original radar point cloud data, and constructs a target motion trajectory. A trajectory smoothness index is calculated. From three dimensions of velocity variation, acceleration variation and motion direction variation, product type aggregation evaluation is performed based on human motion physical constraint parameters, and two-dimensional verification is performed in combination with a signal-to-noise ratio. For real targets and suspicious targets, when occlusion occurs, virtual points are generated frame by frame based on Kalman filter prediction steps, and are dynamically calculated by an environmental complexity factor and adaptively adjusted according to the occlusion time and target speed. A position standard deviation is used as a reliability criterion, and reliable virtual points are inserted into the trajectory to compensate for data loss. The application can effectively eliminate ghost false targets and maintain trajectory continuity when occlusion occurs.
