Simulation of Classification-Aided Tracking Multiple Targets Based on HRRP

In ballistic multiple targets tracking in dense clutter environment,a novel CATNN(Classification-Aided Tracking Nearest Neighbor) algorithm was investigated which fused kinematical information and classifying information based on HRRP. Because of the difficulty in obtaining the real data,a simulative method of dynamically combining tracking and classification was put forward with static simulation data to evaluate the algorithm. In the simulation scene,the performance of CATNN was compared with conditional JPDA and NN algorithm. The results indicate that the CATNN can overcome the track-coalition and false-tracking phenomena,and the demand of algorithm verification can be satisfied with these simulation data.
