Multi–Target Detection and Tracking Using Dynamic Programming

A dynamic programming (DP) multi-target detection and tracking algorithm is developed for the simultaneous detection and tracking of low signal - noise ratio (SNR) targets in passive sonar processing. The detecting and tracking approach is considered as a special problem of multiple dimensional image processing and integrated into a single optimization procedure. The DP algorithm is extended to passive sonar processing and a new trace-evaluation function is proposed in this paper. Numerical simulation result shows the advantage of DP algorithm.
