Exploiting Projection Trajectories Discrepancy for Multipath Suppression and Detailed Feature Extraction of Buildings in SAR Adjacent Sub-Aperture Images

Remote Sensing
In synthetic aperture radar (SAR) imagery of built-up areas, multipath effects generate false targets that closely resemble genuine structural features, severely hindering refined interpretation of building structures.
