An Improved Peak Extraction Algorithm in PHD Based Multi-Target Tracking Algorithm Applied to Passive Radar

To extract the target location correctly in PHD based multi-target tracking algorithm, an improved peak extraction algorithm was proposed. This new algorithm stemmed from the CLEAN technique in radar signal processing. By finding the highest peak in every iteration, the assumed target was extracted and its corresponding location information was obtained. Simulation results prove the efficiency and correctness of this new algorithm.
