摘　　要：天波超视距雷达(OTHR)具有的低数据率、低检测概率和低量测精度特征对目标跟踪提出挑战;由于对航迹、航迹存在概率的平滑作用,基于状态扩维IPDA(As-IPDA)算法在目标跟踪中得以很好应用,文章把As-IPDA算法引入到天波超视距雷达目标跟踪环境中;仿真结果表明,与传统的概率多假设跟踪(PMHT)算法相比,As-IPDA算法在目标跟踪精度、失跟率以及实时性方面都有满意的结果,从而验证了该算法在天波超视距雷达目标跟踪中的有效性、可行性。Sky-wave Over-the-Horizon Radar （OTHR） has a low data rate. low probability of detection and low measurement accuracy , which challenges target tracking algorithm. By means of smoothing the state estimate and the probability of track existence at the same time, As-IPDA algorithm is widely used in tracking targets. As-IPDA algorithm is introduced to OTH Radar for track maintenance. Simulation results show that As-IPDA algorithm has better performance on probability of track loss. estimate precision, execute time compared with Probabilistic Multiple Hypothesis Tracking （PMHT） . It demonstrates that As-IPDA algorithm is applicable and effective in OTHR.
