摘要: 要提高对空中目标的定位导航精度 ,就必须进行电波折射修正 ,该文提出了在机动雷达系统中利用地面气象参数的电波折射误差快速算法 ,并且也进行了精度检验 ;证明了在 4°以上仰角完全可用快速算法代替射线描迹法 ;从而解决了对于机动雷达系统不能快速进行电波折射误差修正或精度较差的问题。这对于提高机动雷达的测量精度具有重要的意义。

Abstract: The radio wave refraction correction for improving the accuracy of the na vigation and location is necessary.Both the quick algorithm of radio wave refraction correction by the ground meteorological parameters and its accuracy are presented and checked for movable radar svstem,respectively.It proves that ray dray mark method can be replaced by the quick algorithm above 4 degree.The problem of the non quick correction and low accuracy for movable radar system are resolved.
