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.
