Wide-angle Ultra-Wideband PolSAR Imaging Simulation of Canonical Targets

By adopting an ultra-wide bandwidth and exploiting a wide-angle synthetic aperture, SAR can achieve high spatial resolutions in the range and azimuth directions, respectively. Incorporate with polarimetry diversity, which allows to explore the polarimetric scattering mechanism of the illuminated targets. Integrated these characteristics aforementioned, wide-angle ultra-wideband polarimetric synthetic aperture radar with canonical targets have been investigated numerically and experimentally. To further validate the simulated results, the corresponding experiment with a dihedral was conducted by a GB-SAR system in the field, which exhibit good agreement with the simulated results.
