Other AbstractIn this paper,pnxedure of the absolute calibration of radar scatterometer is presented. Effects of the far field criterion for the calibration are analyzed. After converting the effft of curvature of spherical wavefront and the amplitude and phase nonuniformity of the incident field to the variation of the radar~section,the concept of eff}tive radar cross section(ERCS) is introduced to unify the calibration formula for near field region and far field region measurement. Using the new formula,a practical near field region absolute calibration scheme is proposed. Absolute calibrations of four scatterometers of S,C,X and Ku band show the validity of the given method.
