一、引言由于实际中跟踪者对目标机动特性的先验知识知道很少,因此,研究如何充分利用目标机动特性的后验知识,实现对机动目标的有效跟踪问题便具有重要的现实意义。Chan,Shalom等人提出的附加机动检测,并以观测残差中提取机动指令的方法,就代表了这一新的研究方向。沿着这一方向,本文在现有处理方法的基础上进行了一些新的探索。要检测机动,首先要确定检测所需点数,即检测窗宽。现有的处理方法是在雷达测距噪声方差б_m~2,天线扫描周期T,目标机动加速度U给定的条件下,通过计算机模拟实验,
I. INTRODUCTION Since the trackers have little prior knowledge of the target maneuver characteristics in practice, it is of great practical significance to study how to make full use of the posterior knowledge of the target maneuver characteristics and realize the effective tracking of maneuvering targets. Chan, Shalom, who proposed the additional maneuver detection, and to observe the residual error in the method of extracting maneuvers, represents the new research direction. Along this direction, this paper makes some new exploration based on the existing treatment methods. To detect maneuvers, we must first determine the number of points required for detection, that is, detection window width. The existing treatment method is based on the radar ranging noise variance б_m ~ 2, antenna scanning period T, target maneuvering acceleration U given conditions, through computer simulation experiments,
