摘要：
There has been significant progress in the application of microwave remote sensing for measuring soil moisture. Both passive and active systems have demonstrated the capability to measure soil moisture, and there have been a number of studies using aircraft and spaceborne data that have demonstrated its usefulness for agricultural and hydrologic applications. However, there are still several unresolved questions regarding the optimal instrument configuration and other target characteristics such as roughness and vegetation. In addition, the most likely disciplines for using these data, agriculture and hydrology, do not currently possess adequate models or procedures to use this new technology.
