说明：  使用matlab程序编写的雷达目标航迹跟踪小例程，主函数是进行雷达数据处理，通过nSHcmq分析，主成分提取，GiIsRwc降噪等处理后得到的运动轨迹曲线。
(Matlab programming using radar target tracking small track routines, the main function is radar data processing, through nSHcmq analysis, principal component extraction trajectory after GiIsRwc noise reduction processing curves obtained. )
