卫星目标光学测量大气折射修正

The Refraction Correction of Optical Measurement to the Satellite

本文从实测的大气参数廓线出发，讨论了对卫星目标进行光学定位捌量时，进行大气折射误差修正时的几个问题，如大气色散、大气湍流和大气水平不均匀性等对折射修正的影响．首先计算了不同仰角下卫星目标光学测量的大气折射修正量的大小，讨论了用不同波长测量时大气色散所造成的修正量的偏差．同时还讨论了大气湍流、大气水平不均匀以及大气条件及昼夜变化等气象因素所引起的折射修正误差．

In this paper, some problems are discussed about the refraction correction while tracing and measuring the satellite using optical method. First, the magnitude of refraction correction is calculated under different elevation. Then the affect of optical dispersion is discussed. At last, some other problems such as atmospheric turbulence, horizontal asymmetry and the dairy variety of refractive are discussed.
