用辐射计进行低角电波折射修正的补偿方法

用微波辐射计进行电波折射修正是一种快速、精确的好方法。但由于它没有考虑电波射线弯曲所引起的折射误差，因此只适用在雷达天线仰角较高的条件，如在低仰角下使用该方法就会产生较大的误差。为了扩大其应用范围，本文提出了用微波辐射计进行低角电波折射修正的补偿方法，并且给出了精度检验结果。

Compensation Method of Radiowave Refraction Correction by Microwave Radiometer at Low-Angle

The radiowave refraction correction by microwave radiometer is a fast and accurate way.But it ignores the bend refractive error,thus it can be used only under the condition of higher elevation.It will lead to bigger losses if the method is used at lower elevation. This paper presents a compensation method of radiowave refraction correction by microwave radiometer at low angle and gives out the result of precision test.
