摘　　要：利用IRST(红外搜索与跟踪)系统所获取的各目标的角度及其红外光谱辐射功率和信息,通过对红外光谱辅射功率和的相关处理,运用选优的JPDA(联合概率数据关联)算法与I MM(交互多模型)算法实现了IRST系统的单站多目标跟踪,并通过两个仿真场景对算法性能进行了检验.仿真结果表明在跟踪开始阶段,两个场景中的每个目标都能获得高精度的跟踪;当目标编队飞行时,算法能对各目标进行有效的跟踪,而且跟踪精确度也是令人满意的;当目标交叉飞行时,跟踪的误差明显加大,随着时间的延续,对远距离目标会失去跟踪能力,但对近距离目标仍能进行有效的跟踪.A method for tracking multiple maneuvering targets with single observer of IRSTS is presented, It is set up by using the information of the bearing measurements and the sum of the infrared radiation power of the targets received by IRSTS and combining the IMM（Interacting Multiple Model） and the JPDA（Joint Probabilistic Data Association） algorithm. The performance of the algorithm is verified by two scenarios of multiple maneuvering targets tracking. The results show that at the beginning of the tracking, both the scenarips can be tracked effectively~ when the targets fly at a forming columns, all the targets can be track effectively at the whole trajectory and the accuracy of the tracking is satisfied; when the targets fly crossly, the RMS position error changes large obviously and give a invalid track to the target at the distance at the end of the trajectory, but the near target can be tracked effectively at the whole trajectory.
