BACKSCATTERING MEASUREMENTS FOR METALLIC UNCLOSED SPHERICAL SCREENS
ABSTRACT
Electromagnetic backscattering measurement results for metallic unclosed spherical screens with changing the probing signal frequency in the range from 26.2 to 38.4 GHz are presented. The radii and aperture of a spherical segment were equal to 18.08 mm and 12.55 mm, respectively. The sample was made by extrusion of aluminum foil with a thickness of 0.15 mm. Frequency dependences of the normalized radar cross-section (RCS) were obtained for excitation of a thin spherical screen along the axis. A comparison between experimental data and known theoretical calculations for RCS is made. Backscattering behavior is studied in the wide range of frequencies and incidence angles.
