摘　　要：针对边扫描边跟踪多频连续波雷达在杂波环境下的多目标跟踪问题,借助JIPDA算法中考虑目标存在概率的思想,并结合该体制雷达能提供高精度的径向速度信息,提出了一种引入径向速度量测的改进JIPDA滤波跟踪新方法。首先介绍了传统的JIPDA算法,然后对引入径向速度量测的改进JIPDA算法进行了理论分析,并讨论了引入径向速度量测和目标存在概率时互联概率的计算,最后进行了仿真实验。仿真结果表明,由于速度观测值提供了有关目标运动的更进一步信息,使得改进的JIPDA算法在跟踪性能上得到了显著提高。In order to solve the multi-target tracking problems in multiple frequency CW radar under a cluttered environment, an improved JIPDA algorithm by using the probability of track existence and high precision radial velocity measurements obtained from this form of radar system is presented in this paper. First, the conditional JIPDA algorithm is introduced. Then, this improved JIPDA algorithm using radial velocity measurements is analyzed in theory, and the computation of association probability considering the target＇s radial velocity information and the probability of track existence is discussed. Finally, simulation results show that the tracking performance of JIPDA algorithm is improved significantly due to the utilization of the radial velocity information.
