Luneberg reflectors principle

The Luneberg reflector is a sphere made of concentric dielectric layers with a metal-plated reflecting surface, encapsulated in a waterlight fiberglass shield.

This device significantly enhances the radar cross-section, or RCS, of any system with little or no RCS and gives a remarkably homogeneous reponse within a wide angle.

Depending on the model, and according to their final use, Luneberg reflectors can reflect incident energy coming from various directions back in a specific zone.

Significant RCS enhancement

Homogeneous response within a wide angle

Calibrated in anechoic chamber

Military applications

This type of reflector allows target spotting for live fire training purposes involving radar-guided missiles and can be integrated to air targets, whether towed, propelled or jet-powered. As far as the equipment of naval targets is concerned, reflectors are fixed on watercraft to amplify their radar signal. For calibrations purposes, Lüneberg reflectors allow to accurately assess radar range

Civil applications

This technology can also be used in satellite communication with multiple beam antennas, airport, sea and river beaconing, as well as in the air navigation aids field.
