摘　　要：在IRST(红外搜索与跟踪)系统的角测量信息基础上,增加了红外探测器对目标红外辐射的响应信息这一测量项,并以相邻两次测量的目标红外光谱辐射功率之比作为伪测量,构造了杂波环境下机动目标跟踪的IMM-PDAF跟踪算法。目标红外辐射响应信息的引入,使IRST系统由一个弱观察系统变为一个可观察系统;伪测量目标红外光谱辐射功率之比的构造,消除了目标红外光谱辐射强度不确定所产生的不良影响。通过跟踪一个高机动目标的仿真过程,对算法性能进行了检验,仿真结果表明:本算法对杂波环境下的机动目标能进行有效的跟踪,而且跟踪的精度也令人满意。The infrared radiation power of the target received by IRSTS is introduced to target tracking for this bearings-only measurements system, with the ratio of the two serial measurements of the infrared radiation power of the target, which eliminated the disadvantage of the uncertainty of the radiation intensity of the target, an IMM-PDAF（interacting multiple model-prohabilistic data association filter） algorithm is established. The performance of the algorithm is verified by simulating the tracking of a highly maneuvering target, the results show that ： the target can be tracked effectively with the method presented and the accuracy of the tracking is satisfied.
