采用多速率多模型交互实现机动目标的全速率跟踪

多速率模型通过对原始测量结果和目标运动模型进行多分辨分解实现目标高精度跟踪.多模型交互方法则采用一个马尔科夫链控制多个模型交互实现机动目标跟踪.本文给出了一种采用多速率多模型交互方式实现机动目标全速率跟踪的方法,它通过交织多次滤波结果使得跟踪能同时保证高精度和全速率.仿真结果及分析说明了该方法较传统的全速率多模型交互算法获得了更好的跟踪效果.

Full-Rate Tracking of a Maneuvering Target Using Multi-rate Interacting Multiple Model Algorithm

Multi-rate models are used to realize a high-grade tracking through the decomposition of the target's original measured results and state model to multi-resolution.A Markov chain is introduced into the interacting multiple model (IMM) algorithm to control the interaction of the several models to realize the tracking of high maneuvering targets.A full-rate tracking method of a maneuvering target by means of interacting among multi-rate models is proposed here.High precision and full-rate of the tracking are guaranteed by interlacing several times' filtering results.Simulation results and analysis demonstrate that compared with conventional full-rate IMM algorithm the new method offers a much better tracking.
