Passive Multitarget Tracking Based on Multidimensional Assignment Algorithm
基于多维指派算法的被动多目标跟踪方案

A new multitarget tracking method based on multidimensional assignment algorithm is developed for passive DOA systems in the paper. The method combines 3D datum line least cost algorithm and dynamic 2D assignment algorithm. The key features of the proposed approach are as follows: First, 3D datum line least cost algorithm is a fast measure data association approach, which cuts candidate associations very fast and reduces the calculations of association costs and completes track initiation. Second, the associations of measurements and tracks are made by dynamic 2D assignment algorithm. Simulation results prove that the proposed algorithm is effective to multitarget tracking for passive DOA system.
