To simulate air targets of various types in the ultrahigh frequency radar range, multilayer spherical Luneberg lenses have become widely used. The reflective properties of such lenses depend on both their absolute dimensions and irradiation frequency, and on the properties of the dielectric material, design features, and their manufacturing technology. This research considers six-layer spherical Luneberg lenses with their uniform division into layers by dielectric permittivity. The calculations performed have shown that the average absolute error in the approximation of the dielectric permittivity to the theoretical law of change when the lens is uniformly divided into six layers by dielectric permittivity is no more than 6.8 %. Theoretical calculations and experimental studies have revealed the influence of the design features of spherical lenses, the characteristics of the dielectric material, and the features of the manufacturing technology on the reflective properties of such air target simulators.
