空基GPS遥感地球大气参数方法研究

探讨了空基无线电掩星技术应用于遥感地球大气参数方法，并将该方法编制成资料处理软件。对实测资料进行处理和分析后，给出了地球大气参数反演结果。发现指数函数外推法引入数据处理后大大改进了大气温度的归算结果，而对气压归算的影响却很小。比对结果显示我们的遥感结果同国外有关结果基本相符。

Remote Sensing of Terrestrial Atmospheric Parameters by Space-borne GPS Radio Occultation

The way of remote sensing of terrestrial atmospheric parameters using space borne GPS radio occultation technique is discusses in this paper.Based on this method, a data analysis software has been coded and is used to reduce real radio occultation data. It is confirmed that exponential function extrapolation contributes much to the improvement of inverted temperature; however it does much less for pressure inversion. Compared with relevant published results from abroad, our results are, at large, agreeable with foreign investigators' relevant works.
