Interferometric SAR calibration with area calibration site of same height

Aimed at the interferometric calibration problem for the Dual-antenna Airborne InSAR, Considering Ground Control Points(GCPs) are limited, calibration site of area with same height such as flat terrain is advanced. A scheme of establishing parameters bias and building Digital Elevation Model (DEM) is designed. Some airborne InSAR data, derived by Institute Of Electronics, Chinese Academy Of Sciences(IECAS), were used to do calibration experiments with the proposed processor. Their results demonstrated it is efficient.
