Abstract The Sarabandi’s Calibration Algorithm(SCA) using distributed targets is modified in the paper. Then the calibration experiment with the Modified Sarabandi’s Calibration Algorithm(MSCA) is carried out, using the uncalibrated image data and calibrated image data from the same scene obtained by SIR-C system L band SAR. Finally, the calibration result of MSCA is compared with that obtained by SIR-C calibration group and the performance of MSCA is verified.
