摘要
IMM(Interacting Multiple Model)滤波算法以混合状态系统的观点为基础,利用一个连续状态的微分方程来描述目标的运动,利用一个离散差分方程来描述目标的机动出现,从而建立了更为准确的目标运动模型。本文对该滤波算法进行了进一步的研究,总结了该算法的特点,指出了影响该算法性能的因素,并进行了细致的分析。
IMM filter arithmetic, based on interacting state system, uses a sequence state differential equation to depict the movement of the object, and also uses a discrete state differential equation to depict the random appearance of the object, so that a more precise model of the object's movement can be built. This paper makes further research into the IMM filter arithmetic, summarizes some features of the IMM filter arithmetic, pointsout some factors affecting on the performance, and at the last it has made a particular analysis of the IMM filter arithmetic.
