摘　　要：通过与无线电探空仪探测数据对比,对双频GPS接收机观测数据反演大气折射率剖面精度以及使用GPS反演结果进行电波折射误差修正精度进行分析。结果表明,使用双频GPS接收机观测数据反演的大气折射率剖面,可以替代无线电探空仪探测的大气折射率剖面,对雷达测距、测角和测速等进行电波折射误差精确修正。Compared with the results using radiosonde measurement data, the precision of atmospheric refractivity profile retrieved by dual-frequency GPS receiver measurement data and the accuracy of radio wave refraction error correction with the GPS retrieving technology are analyzed. The results indicate that the refractivity profile measured by radiosonde can be replaced with the one retrieved by dual-frequency GPS receiver measurement data and the refractivity profile retrieved by dual-frequency GPS receiver measurement data can be used to exactly correct the radio wave refraction error of radar measurement data.
