Blind Azimuth Phase Elimination for TerraSAR-X ScanSAR interferometry

It is a huge challenge to utilise them for interferometry due to the impacts of non-linear azimuth phases and insufficient parameters, although the TerraSAR-X ScanSAR system is able to provide SLC data with both large coverage and high resolution. A Blind Estimation Method for Azimuth Phase Elimination (BEMAPE) is proposed here aiming to resolve these problems through eliminating the azimuth phases blindly. Testing of the method on a pair of TerraSAR-X ScanSAR SLC data has proven its quality and performance, finally making TerraSAR-X ScanSAR interferometry based on SLC data possible.
