Full Polarimetric Non-Specular Scattering of Flat Plate Structures
Abstract
This thesis examined the electromagnetic scattering of a dihedral corner reflector for both monostatic and bistatic source-receiver geometries The full polarization characteristics of the electromagnetic scattering was maintained while the dihedral corner reflector was modeled on and off the principal (horizontal reference) plane. The dihedral corner reflector was composed of two perfectly conducting 9 inch square flat plates joined along a common edge so that they formed an interior angle of 90 degrees. The frequencies of interest included 2, 3, and 10 GHz. THe theoretical modeling utilized the Uniform Theory of Diffraction and the Method of Moments (MOM). The analysis was performed on a Cray X-MP supercomputer and a VAX 11/785 minicomputer. The results from the models were compared with each other, and with measurements for validation. The measurements were taken on the principal plane for same sense and cross polarization components. The MOM model compared well with measurement for the monostatic and bistatic same sense polarization components. However, differences were noted for the cross polarization component comparison. The MOM model was then extended to off principal plane geometries, which was not measured. A substantial amount of cross polarization scattering was predicted for off principal plane geometries.
