Methods of Coordinate Transformation for Air Defense C^3I

介绍一种适合防空C3 I系统的坐标变换方法 ,即在考虑地球表面曲率的前提下 ,把目标坐标从雷达站球面坐标系变换到指挥中心的三维直角坐标系中。先把目标坐标从球面坐标系变换到相对于雷达站的直角坐标系内 ,然后进行坐标原点平移和坐标轴转动。给出了详细的推导过程和精确的坐标变换公式 ,并对结果进行了分析与比较。

This paper discussed a method of coordinate transformation for air defense C 3I. On the precondition that the curvature of earth's surface was considered, translate the coordinates of targets from the radar station spherecoordination-system into the command center three-dimensional right-angle corrdinates system. First translate the coordinates of targets from spherecoordination-system into three-dimensional right-angle coordinates system, then move the origin and rotate the axes. The detailed deducing and accurate formula of coordination transformation are presented, the result is analysed and compared also.
