Keywords: Synthetic aperture radar, interferometric calibration, 3D reconstruction model, sensitivity equations Abstract. The accuracy of system parameters is one of the key factors that limit the precision of DEM from airborne dual-antenna InSAR, so the interferometric calibration is of great significance. The traditional calibration method establishes the sensitivity equations to solve the different calibration parameters biases. This paper presents a new calibration method to improve the algorithm stability and suit for mass production. It introduces sensitivity analysis of every interferometric parameter and establishes a new model based on sensitivity equations. Finally, a set of airborne interferometric SAR data are adopted to do the experiment to illustrate the availability of the new method.
