Calibration of multi-strip airborne InSAR data is needed in order to generate DEMs over large areas.We propose an interferometric calibration method for multi-strip InSAR data.The method can reduce the GCP number using connected points in the overlap area between strips and is shown to be effective by the experimental simulation. The results indicate that the interferometric parameter error of each strip can be calibrated accurately with a reduced number of GCP which could reduce the difficulty of InSAR outer calibration.
