为了探究利用 GNSS-R 信号探测干雪深度的可行性,提出了基于GNSS-R干雪深度检测的方法。通过分析欧空局(ESA,European Space Agency)在南极洲收集的干雪实验数据,可以得到在干雪深度大约为10 m、85 m、135 m、225 m的地方有较多反射信号被接收机接收,形成明显峰值。在相同几何条件下,仿真得到的雪深结果与真实数据结果有很好的一致性。

In order to explore the feasibility of detecting the depth of dry snow using GNSS-R signals, a method of detecting the depth of dry snow based on GNSS-R was proposed. Through analyzing the experimental data of dry snow collected by ESA (European Space Agency) in Antarctica, we can make a conclusion that some more reflected signals received by receiver located at 10 m, 85 m,135 m,225 m depth respectively, which formed obvious peaks. Under the same geometrical condition, the results of snow depth obtained by simulation is in good agreement with the results of real data.
