Though SAR remote sensing has been expected as an efficient rice crop monitoring tool, there still exist non-negligible mysteries to extract physical parameters. To solve the problems, it is essential to conduct theoretical characterization of experimentally obtained radar backscatter from rice paddies. In this paper, rice paddies in Niigata city, Japan, were observed by an L-band full polarimetric SAR, by systematically varying the incidence angle and polarization. Bragg scattering was obvious in the SAR imagery at L-band, and it was theoretically modeled. Then, backscatter from the rice paddy suppressing the Bragg scattering effect was obtained by utilizing the model.
