N2 - Ground-based synthetic aperture radar (GB-SAR) systems are primarily used to enhance the understanding of the complex mechanisms underlying microwave backscattering. In this study, a polarimetric calibration procedure is applied to GB-SAR data, effectively reducing channel imbalance during post-processing and thereby improving image quality. Two types of corner reflectors (CRs) - a dihedral reflector oriented at 0 and 45, and a trihedral reflector - are employed as reference calibration targets for polarimetric radar calibration methods. Subsequently, small unmanned aerial vehicle (UAV) test object is analyzed. The results demonstrate that the polarimetric signatures obtained after calibration accurately correspond to the expected scattering responses of the test target.
