摘要
多模型粒子滤波(MMPF)是一种低信噪比条件下对机动弱目标进行有效检测的检测前跟踪(TBD)方法,但是其性能受各种参数影响。该文对MMPF算法的模型转移参数进行研究,并通过仿真分析和对比,得出一些有益的结论。
The multiple model particle filter (1VIMPF) is an effective track-before-detect (TBD) solution to maneuvering weak target in low SNR environment. However, the performance of the MMPF is influenced by a set of parameters. This paper stud- ies the impact of model transitional matrix on the performance of the MMPF. Through the simulation, analysis and comparison, the paper gives some helpful conclusions.
