Abstract Because of the multiple-beam scanning strategy in swath, the intrinsic periodic scalloping exists in ScanSAR, which affects the radiometric property of ScanSAR. Based on the character of ScanSAR, the mechanism and property are studied, radiometric error caused by scalloping and relation between Doppler centroid error and scalloping are quantificationally analyzed. The residual error after correction is also studied.
