分析了直角坐标系下交互式多模型概率数据关联（ＩＭＭＰＤＡ）算法的并行机理。将实现该算法的任务分配到高速并行仿真计算机上，得到了并行ＩＭＭＰＤＡ算法。研制完成了机动多目标跟踪并行仿真软件包，对并行算法性能进行了测试。仿真结果表明跟踪精度和并行效率良好。
The parallel mechanism of interactive multi-model probability data association (IMMPDA) algorithm in Cartesian coordinates is analyzed. The task of realizing the algorithm is distributed to the high speed parallel simulation computer, and the parallel IMMPDA algorithm is obtained. Developed a mobile multi-target tracking parallel simulation software package, the performance of parallel algorithms were tested. The simulation results show that the tracking accuracy and parallel efficiency are good.
