摘要：

The characteristics of the polarization ratio in the case of rough surfaces are investigated. In addition, an inversion method is also proposed for retrieving the surface roughness over land and sea. The proposed method was effective for angles of incidence near the Brewster angles close to the view angles of many satellite microwave sensors. This new method retrieves the sea surface roughness within a reasonable range of bias. Consequently, this study provides insight into the polarization ratio and an inversion method to estimate the surface roughness by using the characteristics of the polarization ratio from passive microwave remote sensing.
