SAR image rapid co-registration based on RD model and coherence interpolation

摘要

According to SAR image side-look geometry principle, this paper discussed the geometry co-registration, coherence coarse co-registration and coherence matrix over-sample fine co-registration. The accuracy is from low to high. In the end, the experiment was carried out using the SAR image pair that was collected by ERS-1/2, and the result was correct.
