چکیده :

Luneburg reflector is a spherical passive microwave reflector usually used for RCS enhancement. Luneburg reflector has three modes: monostatic, bistatic, and equatorial. The main idea of this paper is to study and analyze the RCS of the Luneburg reflector and increases its angle of aperture in bistatic mode. The electromagnetic behavior of this reflector is analyzed with the Mie-Lorentz theory. Also, the experimental test results are used in this analysis. The effective parameters of this reflector, such as reflector radius, cap radius, operating frequency band, and permittivity of the reflector, are studied in this work. The Luneburg reflector pattern is presented in both the azimuth constant and elevation constant to determine the proper orientation of the reflector toward a target. This is crucial when maximizing the RCS is needed. Last but not least, challenges with designing of Luneburg reflector for operating in bistatic mode are discussed, and a reflector is designed to operate at the mm-wave range.
