摘　　要：将交互式多模型(IMM)算法应用到具有隐蔽性的无源时差定位系统中,找到了一种适合于无源时差定位系统跟踪机动飞行目标的混合模型即常速度(CV)模型与Singer模型组成的混合CV Singer模型。在各种现有算法中,基于该混合模型的交互多模型算法可获得较好的定位跟踪效果。另外,将该混合系统与CV CA模型组成的混合系统进行了比较,进一步证明了该混合模型的有效性。The interacting multiple model (EMM) algorithm is applied to the TDoA (time difference of arrival) passive location system and a hybrid CV-Singer model which can be used to track maneuvering targets is presented. Simulation results show that the hybrid model can provide an ideal tracking performance. Compared with the IMM algorithm based on CV-CA model, the EMM algorithm based on CV-Singer model is proved to be more effective for the TDoA passive location system.
