RCS measurements of plate geometries with theoretical verification

The rectangular plate is an important scattering geometry for examining multiple interactions between parallel edges, grazing-incidence scattering, corner-diffraction effects, and radar cross section reduction due to thin coatings. The authors present measurements, performed in an anechoic chamber, of several rectangular flat plate geometries, designed to emphasize the important scattering mechanisms that can be observed. High-frequency models, such as the method of equivalent currents for half-planes and for right-angled corners, and the uniform theory of diffraction, are used for verification and to illustrate weaknesses that still exist in high-frequency modeling techniques.<>
