Sentinel-1 Azimuth Subbanding for Multiple Aperture Interferometry - Test Case Over the Roi Baudouin Ice Shelf, East Antarctica
As an extension of Synthetic Aperture Radar Interferometry, Multiple Aperture Radar (MAI) is a spectral diversity technique that allows the determination of azimuth displacements from phase shift measurements. This is made possible through the creation of backward- and forward-looking Single-Look-Co...
