Abstract
Recently, microwave remote sensing has become a strong tool for monitoring the surface of the earth. As a potential application, the monitoring of the surface distribution of soil moisture content is an important factor in hydrology. The differential scattering coefficient data obtained from a satellite borne scatterometer depends on the complex dielectric constant, which relates to the moisture content in the soil. The paper describes the results of the investigation of the soil moisture content characteristics of Kanto-Loam. In this paper the estimation results of the differential scattering coefficient depending on the roughness of the soil surface are reported. A fairly good agreement is obtained between the measured results and the theoretical results using the integral equation model proposed by F.T.Ulaby.
