摘　　要：静止单站对多目标进行纯方位跟踪时,若在直角坐标系下建立跟踪模型并使用最近邻标准滤波器(NNSF)进行关联和滤波,结果通常不稳定且容易发散。针对此问题,提出将修正的极坐标系(MPC)下的扩展Kalman滤波算法及联合概率数据互联关联(JPDA)算法相结合。与NNSF-MPC算法的仿真对比试验表明,JPDA-MPC算法可以提高跟踪过程的稳定性,且具有更小的跟踪误差。When tracking multiple bearing-only targets with a single station, the results are usually unstable and tend to be divergent, if the tracking model is built in Cartesian coordinates and the NNSF algorithm is used for data association. For resolving this problem, the extended Kalman Filter in MPC and the JPDA algorithm are combined. Simulations show that, compared with the NNSF-MPC algorithm, the JPDA- MPC algorithm can improve the stability of tracking process and also has a smaller tracking error.
