| 摘 要： | 目前的实时弹道处理过程中,由于获得探空气象数据比较困难,电波折射误差均采用各种简化方法进行计算,因而大气折射误差计算的精度不高,修正效果不佳。针对这种现状,本文提出了基于双指数模型的射线瞄迹法计算大气折射误差。试算结果表明,该方法的计算精度与事后数据处理所采用的电波折射误差修正方法相当,且能够满足实时处理的时间要求。

| Abstract: | Simplified methods are often used to compute radio wave refraction errors in the course of real-time data processing as it is difficult to obtain real weather data acquired by sounding rockets.As a result,the accuracy of atmospheric refraction error computation is not high and the correction effect is not desirable.To solve this problem,improved radial track method based on dual-exponential model is presented in this paper.Trial computation shows that the method is feasible for real-time data processing in ... |
