摘要
针对现有实时电波折射修正方法的不足,通过对距离和仰角电波折射误差影响因素进行分析,充分考虑各测站气候的差异,建立与测站历史气象数据相关的修正模型,并在此基础上提出了一种关于对流层电波折射实时修正新方法。同时以实测数据为例,对该方法和其他传统方法的修正效果进行比较,结果表明该方法同时具备实时数据处理的速度和事后数据处理要求的精度。
To make up for the discrepancy of existing atmospheric refraction correction methods used in realtime and post data processing,this paper establishes a correction formula from statistics of the historical meteorological data of measurement stations based on analysis of the atmospheric refractive error factors of distance and elevation and taking into consideration of climate differences of measurement stations.Then,a new realtime atmospheric refraction correction method is proposed.Mission data is used for comparison of the method with conventional methods.The result shows that this method achieves not only the speed of realtime processing but also the accuracy of post data processing.
