%X Various factors leading to error in spaceborne SAR radiomctric calibration are discussed, and an equation to estimate the radionretric calibration error is proposed. The equation for calculating SAR imaging processor gain based on chirp scaling algorithm is derived, and testified through computer simulation experiments. A quantitative conclusion on the contribution of imaging processor gain to SAR radiometric calibration error is obtained.
