摘要
我们利用模式大气建立了一种全球平均折射率高度分布的伽马函数模型,计算结果指出该模型比常用于射频的指数分布具有更好的效果。为了检验全球折射率模型的适用性,利用典型地区的气候资料进行了比较,结果表明全球平均模型可使大气折射修正误差不超过1m,如果采用本地区的平均模型,有可能使测距误差限制在0.2m左右。
Using a model atmosphere, We set up a global model of atmospheric refraction--indexprofile. Calculation shows that the model is better than exponent model which is used inradiofrequency.In order to examine the applicability of the global model, a comparison bet-ween. the model and climate data of several typical region is performed.The results presentthat the corrected residual error reduced by atmospheric refraction can be less than l mfor using the global model.If the average model of local region is used, the ranging errorwill be within the limits of 0.2m or so.
