Measurement of polarimetric RCS characteristics of canonical targets under GB-SAR environment

This work presents a novel aspect for measurement and implementation of a radar cross section (RCS) using the polarimetric backscattered power under ground-based Synthetic Aperture Radar (GB-SAR) environment. Special attention is given to combine the GB-SAR principle with RCS measurement in order to determine the polarimetric backscatter characteristics of canonical targets along the azimuth direction. In this paper, the polarimetric measurement concept using GB-SAR environment for the movement of pyramidal horn antennas in the azimuthal direction are developed. The experimental results are presented with implementation of dihedral and trihedral corner reflectors. The results based on this methodology allow to generate the backscattered characteristics of canonical targets with reference to measurement geometry under GB-SAR environment. Consequently, the measurement concept and the experimental results can be used to determine and to identify the specific geometry of the objects in searching applications.
