Investigation of multiple target location in vector miss distance measurement system

The location algorithm, using the distance difference obtained from the phase difference, is used to estimate the moving target´s position. To execute the vector miss distance measurement of the multi-target, this paper presents the combined location algorithm and data association algorithm to identify the multiple target tracks, and utilizing fixed-interval Kalman smoothing filter to improve precision of the miss distance. The simulation results of the performance indicate the feasibility of the algorithm.
