This project aims to use the microwave communication links of low earth and/or medium earth orbit satellites to achieve three dimensional tomographic reconstruction of rainfall. The path loss of microwave signals due to rainfall, known as rain attenuation can be used to measure rain. Similar to using X-ray to carry out human-body CT scans. With the aid of advanced signal processing techniques, the proposed method will achieve 3D measurements with resolution and coverage unachievable before, paving the way for innovative water relevant applications such as hydrology and agriculture, and new findings in atmospheric research.

该项目旨在利用低地球和/或中地球轨道卫星的微波通信链路实现降雨的三维层析重建。由降雨引起的微波信号的路径损耗，称为雨衰减，可以用来测量降雨。类似于使用X射线进行人体CT扫描。借助先进的信号处理技术，该方法将以前所未有的分辨率和覆盖范围实现3D测量，为水文学和农业等与水有关的创新应用以及大气研究的新发现铺平道路。
