空中机动目标刚体运动建模方法

传统目标跟踪和识别算法通常建立在目标质点运动模型的基础上,其实现过程相对简单,但也存在精度不高的缺点.随着现代雷达、目标跟踪/识别技术的发展,以及各种高精度目标测量传感器的运用,建立更精确的刚体运动模型已成为一种必然需要.概述了国内外在空中机动目标刚体运动建模这一领域的研究现状,并详细介绍了当前常用的几种空中机动目标刚体运动建模方法,最后,根据分析总结了当前这些建模方法存在的缺陷,并指出了其可能的研究方向.

A Methods for Modeling Rigid-body Motion of Airborne Maneuvering Targets

Traditional target tracking and recognition algorithms are based on Particle Motion Model (PMM), and its implement is relatively easy, with the disadvantage of a low accuracy. With the development of modern radar and target tracking/recognition technologies, as well as the utility of all kinds of high-accuracy measuring sensors, it has become a necessary trend to set up a more precise Rigid-body Motion Model (RBMM) of target The paper summarizes national and international development of the field of setting up RBMM of airborne maneuvering target, and introduces several usual methods of modeling the motion in detail At last, the authors analyses the limitation and disadvantages of these methods according their knowledge, and points out several possible researching directions in the field.
