探讨了一种利用单个观测站对机动辐射源目标进行无源定位与跟踪的交互式多模型（IMM）算法。在该方法中，基于辐射源的信号到达时间（TOA）和信号到达方向（DOA）信息，可以实现单站无源定位，运用交互式多模型算法，可以适应目标的机动性。通过计算机仿真，验证了该方法的正确性和有效性。

The Interacting Multiple-Model (IMM) algorithm for passive localization of maneuvering emitter by mono-static is discussed in this paper. Based on the Time of Arrival (TOA) and the Direction Of Arrival (DOA) of the emitter, passive localization by mono-static is practicable, and also the localization of maneuvering emitter is practicable with the IMM algorithm. With the help of computer simulation, the method is proven to be correct and effective.
