摘要

本文就球坐标中的机动目标跟踪

特别是用舰上跟踪雷达对来袭的飞航式反舰导弹进行跟踪的问题提出了一套新的模型和算法.这个新的模型着重于对球坐标系中目标运动模式和加速度非线性关系的深入分析.同时本文提出了一种称为二级自适应滤波器组(TSAFG)的自适应跟踪滤波器结构.对于满足一定条件的机动目标

这一方法具有简单、灵活、有效的优越性.它还可推广到在球坐标系中对多种类型的机动目标进行精确跟踪.

Abstract

A new motion model with a tracking algorithm is introduced in this paper to track a maneuvering target such as a sea-skimming anti-ship cruise missile (ASCM) in spherical coordinates.The algorithm is based on a more accurate analysis of the motion of maneuver targets.Unlike previous models that treat uncertainties introduced by maneuvering as general random process

this model takes emphasis on nonlinear relationships between maneuver accelerations.A modified adaptive two-stage Kalman filter

named Two-Stage Adaptive Filter Group (TSAFG)

is implemented with this model to track simulated incoming ASCM and other maneuvering targets.It is manifested that the proposed method is simple and effective under many situations

and can be extended to track various types of maneuvers.
