| 摘 要： | 雷达对目标进行搜索和跟踪时,由于雷达的体制、安装方式(运载体还是地面固定位置)、工作方式等的不同,涉及到许多坐标系。结合实际工程问题,对雷达搜索与跟踪中坐标系问题进行了深入探讨。包括坐标系的定义、作用、坐标系转换问题,坐标转换中的误差定量分析,所得出的结论对于雷达对目标进行搜索与跟踪,尤其是对安装于运载体上的雷达坐标系问题有很大的参考价值,并给出了某型直升机载雷达挂飞时的实测姿态数据。

| Abstract: | Numerous of coordinates were involved in radar searching and tracking due to the radar systems and installation modes.Combined with the practical engineering problems,the coordinate problems were analyzed throughly in this paper.The following problems were discussed:coordinates definition and their applications,the transfer between them and the transformation error.The results offered important reference values to radar searching and tracking,especially when the radar was installed in the moving carrier.More important,the real inertial system data in the heliborne radar was offered in this paper. |
