摘　　要：在雷达数据处理中,需要把不同雷达坐标系下的数据融合到同一坐标系下。即要把不同坐标系下的坐标进行相互转换。针对此问题,提出利用向量投影法实现各个雷达坐标数据相互转换的新方法。该方法不同于以往的旋转平移坐标系转换的常用方法,直接利用向量之间的几何关系做坐标变换,计算简单快捷,具有宽广的应用前景。In the radar data processing, the observed data should be converted to a common coordinate system firstly. That is, the coordinate should be converted to each other. According to this, this paper provides a new method based on the vector projection to convert the coordinate. This method is much more convenient than the usual rotation-translation method. C, eometric relations between vectors for coordinate transformation is used, which is proved to be simple and convenient, and can be widely applied to other science fields.
