Abstract
The paper presents a novel approach for the airborne InSAR system imaging processing with motion compensation and automatic registration.Basing upon the feature of the dual-antenna radar data from the airborne InSAR system and using the high precise POS data,the novel approach can accomplish the position error compensation,interferometric phase error compensation and automatic registration of the InSAR image-pair directly at the imaging processing stage.The practical results indicate that the proposed approach is very suitable for the imaging process of a dual-antenna airborne InSAR system with its efficiency in improving the image quality and enhancing the image-pair coherence.
