摘　　要：无线电波在大气中传输时受大气中不均匀介质的影响,会产生电波折射效应,使得地面定向天线在利用GPS数据进行数字引导跟踪目标时产生折射误差,导致链路质量下降或中断。针对此问题,通过对流层大气折射修正技术研究,结合航空测控实际情况,提出了利用基于地面参数预测的线性分层法对大气折射效果进行修正的解决方法,给出了补偿算法,据此进行仿真并在工程中进行试验验证,取得了预期效果。Due the influence of the inhomogeneons anisotropic medium, transmission of radio waves in the atmosphere will produce wave refraction effect. As a result, a error will occur in the GES antenna digital guidance, and there will be unexpected link quality or link interruption. In order to solve this problem, through the process of atmosphere refraction correction techniques, based on the actual property of TT＆C finks, a solving method of linear stratification refraction correction with ground-based parameters prediction was given in this paper, the compensation algorithm was proposed also. Finally, Expected results are obtained in the engineering application.
