| Abstract: | A C band radar calibration method is presented. The experiment has been conducted in an agricultural area near Paris on three different types of surface: wheat stubble, sugar beet, and corn. It has been found that the sensitivity of radar backscattering coefficient δ0 to surface soil moisture agrees well with the results obtained by Ulaby et al. (1979) when soil moisture values are expressed as percentage of the field capacity. |
