| 摘 要： | 提出了一种新的模糊目标跟踪算法--CPDA算法。这个算法在空间多分辨率框架下应用概率数据互联算法,在粗分辨率上实现模糊目标跟踪。在不同虚警密度的模糊目标环境下,利用仿真实验分析了CPDA算法的跟踪性能,同时将其与单分辨率上的联合概率数据互联方法进行了性能比较。仿真结果表明,CPDA算法的跟踪性能在达到与单分辨率上JPDA算法同样性能的条件下,能够以较小的计算量跟踪模糊目标。

| Abstract: | A new dim target tracking algorithm named CPDA is proposed. The probabilistic data association algorithm is applied in the spatial domain multi resolution frame and target tracking is implemented at the coarse resolution level. Two dim target environments based on different false alarm numbers are designed. Simulation tests based on these environments are used to analyze the tracking performance of CPDA algorithm and compare it with the joint probabilistic data association algorithm in the mono resolution level. It is shown from the simulation results that when the performance of CPDA algorithm is almost identical to that of JPDA algorithm in a mono resolution level, the computation burden of CPDA algorithm is lower than that of JPDA algorithm. |
