  • The SAR internal calibration (SIC) technique includes the Internal calibration (IC) theory, IC strategy and highly stable IC instrument. In this paper, the IC technique of a spaceborne SAR system, which employs the TWT (Traveling wave tube) transmitter, is discussed. A method to process the internal calibration data is proposed, the precision analysis of the SIC is given and the effectiveness of the proposed method based on the experimental SAR image is demonstrated.
