基于IMM的估计算法对机动目标跟踪的比较

Comparison of Estimation Algorithms based on IMM in Maneuvering Target Tracking

机动目标跟踪一直是倍受关注的问题,而交互式多模型方法(IMM)是解决这类问题的经典方法。由于传感器的发展或受某种客观条件的限制等,产生了各种基于IMM的算法。为此,介绍了IMM及基于IMM的几种经典估计算法,对它们进行比较研究,并通过机动目标跟踪的仿真算例说明各算法的适用条件、原理、异同点、性能及复杂性,对机动目标跟踪估计器的选择有重要参考价值。

IMM （interacting multiple model） is a classical method to solve problem of maneuvering target tracking. Because of sensors＇ development and some condition constraints, all kinds of algorithms based on IMM are presented. The IMM and some classical estimation algorithms are introduced and compared in the paper. Applicable conditions, principles, similarities, differences, performance and complexities of the algorithms are analyzed through a maneuvering target tracking simulation example.
