摘　　要：基于对流层折射的准实测值,讨论了指数大气模型的合理性。根据9km高空折射率值的稳定性,总结出一种预报距离误差的简易方法;并从理论和实测上,讨论并验证了该法的精度。此外,还给出了统计回归折射误差的新参量并验证了它的有效性,特别是对距离误差的改进。Based on the quasi-measured values of tropospheric refraction,it is discussed that the exponential atmospheric model is reasonable, and according to the stable fea-ture of refractivity at 9 km above sea level, a simplified method to predict tropospheric range error is presented, and the accuracy of which is discussed. Besides, some new parameters for linear regression of tropospheric refraction are given, the improvement in prediction ef range error is distinct.
