An Image Co-registration Method for Wide-swath and High-resolution Spaceborne InSAR
In this paper,we analyse the issue of SAR image coregistration for wide-swath and high-resolution spaceborne InSAR. A solution to this problem is proposed in which three processing procedures are adopted.First,image co-registration pre-processing is performed. There are two methods for this step:one is based on InSAR orbit and radar system parameters,and the other is based on the cross-correlation information of the master and the slave image.Second,coarse co-registration is implemented by block processing.Finally,fine co-registration is executed in order to obtain sub-pixel co-registration accuracy.Data simulation and qualitative analysis of coherence show that this method can provide accurate co-registration for wide-swath and high-resolution spaceborne InSAR,and meet the practical engineering requirement.
