Abstract
The backscattering coefficients observed by synthetic aperture radar (SAR) are influenced by surface geometric roughness obstacles. Using this attributes, spatial distributions of aerodynamic roughness parameter are estimated from the SAR images obtained by the Japanese Earth Resources Satellite (JERS-1). By the method, it is possible to make roughness maps which are very similar to roughness maps derived by the method proposed by Kondo & Yamazawa (1986) which uses the National Land Numerical Information.
