Interacting Multiple-model Algorithm for Passive Location of Maneuvering Target by Multi-sensor

将交互式多模型(IMM)算法与集中式融合跟踪算法相结合,给出了集中式交互多模算法(C IMM);基于目标的多普勒频率差和信号到达方向信息,利用C IMM算法对机动目标进行无源定位与跟踪,并与变维(VD)滤波算法的跟踪性能进行了比较。通过计算机仿真验证了C IMM算法是有效的,且该算法与VD算法相比定位精度更高、稳定性更好。

The interacting multiple-model algorithm with multi-sensor central fusion tracking algorithm is incorporated and the central interacting multiple-model algorithm is given out. A maneuvering target is tracked by the use of central interacting multiple-model algorithm and the result is compared with that of variable dimension algorithm. The simulation results show that the central interacting multiple-model algorithm is effective and at the same time is more accurate and stable than variable dimension algorithm.
