| 摘 要： | 在防御体系中雷达对低空目标一般呈俯视状况,因此在电波折射修正中必须把地球视为椭球,而不能视为圆球体,否则会产生很大误差.本文通过雷达测量参数和大地坐标与空间坐标的转换,给出了计算雷达电波射线上任意一点对应地球半径的方法.

| Abstract: | Radar usually down-looks at targets at low altitude in a defense scenario. The earth must be regarded as an ellipsoid so that earth radius corresponding to any point on radar wave can be calculated. Based on conversion of radar measurement parameters from geodetic coordinates to space coordinates, a method is presented for calculating earth radius corresponding to any point on radar wave. |
