摘　　要：一般常用电波折射误差修正方法存在计算复杂且不具有实时性缺陷.提出了一种电波折射误差修正的新方法,即用微波辐射计采用大气遥感的方法进行电波折射实时修正.它不仅具有全天候、实时性、机动性等特点,而且由于它直接测量出电波传播路径上的大气附加时延积分,从而直接给出距离误差修正量,因此其精度较高.Radiowave refractive errors correction methods have defect of computing complexity and no real time in common use. A new method of radiowave refractive error correction is given, which adopts atmospheric remote sensing by microwave radiometer. It not only has property to suit all weather condition, real time and movement, but also directly gives error correction value of distance by direct measure of atmospheric additional time delay integral. So the accuracy of this method is higher.
