Abstract :Ground-based synthetic aperture radar insert ignore into journalissuearticles values(GB-SAR); systems are mostly utilized to be practical practices in improved understanding of the complex mechanism of microwave backscattering. They also provide complementary information on evaluating the validity of the polarimetric analysis of air-borne or satellite-borne SAR applications. This study investigates some capabilities of polarimetric L-band GB-SAR imaging by testing its performance against a typical terrain and various kinds of manmade targets. Trihedral corner reflectors are also included in the analyses because of their importance in data calibration. Polarimetric backscattering signatures of different targets are analyzed in terms of qualitative assessment of amplitude images and identification and classification of scattering mechanisms through target decomposition techniques. The findings of these analyses and detailed discussions are presented. Specifically, the entropy/mean-alpha insert ignore into journalissuearticles values(insert ignore into journalissuearticles values(H/α ̅);); classification results are shown to be capable of clearly identifying the dominant scattering mechanisms occurring within the investigated scene.
