Application of microwave radiometer in the refractive error correction of radar measurement data

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.
