摘要：

Surface roughness has a significant effect on the relationship between radar backscatter and soil moisture, In order to use existing radar satellite data for soil moisture, roughness effects must be corrected. A technique is presented that utilizes the data bases from soil erosion studies and soil moisture remote sensing investigations to provide first order estimates of the roughness parameters.
