摘　　要：基于用微波辐射计实时测量反演大气折射率剖面的研究,并与施放气象探空仪直接测量的结果进行比对,结果表明微波辐射计实时测量反演得到的大气折射率剖面能够较好地反映雷达站所在地的折射率分布。将反演和实测折射率剖面应用于某次雷达测量数据的电波折射误差计算中,由修正量比对残差分析结果得出:将微波辐射计实时测量反演的大气折射率剖面用于电波折射误差修正是有效的。为微波辐射计应用于高精度机动测控雷达,提高测量数据处理的精度提供了理论和试验依据。Based on the study of atmospheric refractivity profile（RP）retrieved by microwave radiometer（MR）,and compared with the radiosonde measurement data,the result indicates that the RP retrieved by MR could reflect the distribution of refractivity at the radar stations.By applying the two RP to calculate the radiowave refraction error of radar measurement data,the residual error shows that it is effective to apply the RP retrieved by MR to the radiowave refraction error correction of radar.It provides the theoretical and experimental basis for applying MR to high-precision maneuvering radar and improving the data processing precision.
