| Summary: | 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. |
