传统被动相干定位系统(PCLS)利用固定的观测站和外辐射源(IO)实现对目标的跟踪，而这种体制无法应用于真实的海战场环境。针对这种不足，提出了一种基于多个机动观测站和单一机动IO的PCLS目标跟踪模型。针对仅利用到达时间(TOA)的PCLS目标状态估计精度不足的问题，该模型以TOA和多普勒频率的联合测量信息为目标观测量，以信号到达角(AOA)为IO观测量，实现对目标和IO的同时跟踪。仿真结果证明了模型的有效性。

The Passive Coherent Location System (PCLS) uses a fixed observer and an non-cooperative Illuminator of Opportunity (IO) to track targets, which is not applicable to a real sea battlefield environment. In response to this deficiency, this paper proposes a PCLS target tracking model based on multiple maneuvering observer and a single maneuvering IO. For the problem that the PCLS target state estimation is imprecise by only using Time of Arrival (TOA), the model takes the joint measurement of TOA and Doppler frequency as the target observation, with the signal's Angle of Arrival (AOA) measurement as the IO observation, so that simultaneous tracking of targets and IOs is achieved. The simulation results prove the validity of the model.
