In this paper, first compared different receive channel schemes for InSAR application, then the main principal and technique of three practical internal calibration schemes are analyzed and compared, especially the famous SIR-C and X-SAR internal calibration system. Based on these different schemes, a new internal calibration scheme using microwave over fiber link is subscribed.
