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 In this paper, a new model and algorithm are proposed for tracking maneuvering targets in spherical coordinates, especially the tracking of incoming flying anti-ship missiles with ship-tracking radar.The new model focuses on the calculation of spherical coordinates In this paper, an adaptive tracking filter structure called TSAFG is proposed in this paper.For a maneuvering target that satisfies certain conditions, this The method is simple, flexible and effective.It can also be extended to accurately track multiple types of maneuvering targets in a spherical coordinate system
