摘　　要：无线电波在大气中传播时,由于大气的时变特性,会使电波射线产生弯曲,以至雷达测距产生误差,从而导致外测系统在测速定位、导航中产生折射误差,因此要提高雷达测量精度,必须进行电波折射误差修正。文中提出了用辐射计进行电波折射修正的方法,并给出了低仰角时大气时变特性对电波修正精度影响的典型结果。The ray will bend due to time - vriant characteristics of the atmosphere when the radio wave travels in it, which leads to curving effect so that radar ranging produces errors, as a result, the refracting errors wiU be made about outside -examination system in navigating and testing speed, so the radio wave refracting correction must be improved in order to better measure precision of the radar measure. This paper presents the wave refracting method of revising with radiometer, meanwhile the typical result of time - variant riant characteristics＇ influence on the wave＇s revising precision in the atmosphere at low angle of elevation.
