Passive reflector
Web11 Dec 2024 · The Luneberg lens is a passive radar augmentation device used to increase the radar reflectivity of a target without the use of additional energy The lens reflector is a sphere in shape, usually composed of concentric dielectric shells. WebA " reflector " is slightly longer (around 5%) than a half-wavelength. It serves to reflect the radio waves in the opposite direction. A " director " is slightly shorter than a half-wavelength; it serves to increase the radiation in a given direction.
