A ViSAR Shadow-Detection Algorithm Based on LRSD Combined Trajectory Region Extraction

open access: yesRemote Sensing, 2023
Shadow detection is a new method for video synthetic aperture radar moving target indication (ViSAR-GMTI). The shadow formed by the target occlusion will reflect its real position, preventing the defocusing or offset of the moving target from making it ...
