Abstract
A Luneberg lens with a polarization-sensitive spherical 'leaky' reflector cap having conductive strips aligned at a 45.degree. angle to the linear polarization of the incident wave. The ratio of strip width to strip spacing is preferably chosen to reflect back a cross-polarized component about -10 db below the reflected self-polarized component. The strip width is small as compared to the focal spot diameter of the lens for any given incident wave direction and also small as compared to the wavelength of the incident wave. The lens and reflector can be used in small drone aircraft to simulate the radar cross section of a larger body such as an aircraft whose radar cross section causes reflected polarization components not present in the incident field. The full specification must be consulted for an understanding of the invention.
