Double Convex Lens for Marine Retro-Reflector Application

Gray, D., Thornton, J. and Le Kernec, J. (2022) Double Convex Lens for Marine Retro-Reflector Application. In: IEICE Technical Committee on Antennas and Propagation (AP), Matsuyama, Japan, 14-16 Sep 2022, pp. 5-10.

Abstract

Polyethylene 4 free space wavelength radius spherical lenses fitted with 140° spherical metallic cap were found to satisfy the ISO8729 RCS requirement for use on buoys and small fishing and leisure boats. Double convex polyethylene lenses were trialed as a reduced mass alternative to the spherical lenses. An initial prototype fitted with custom reflector back plate shaped to follow the lens focal arc satisfied ISO8729 across a 60° arc. The double convex lens had 25% the weight of a spherical lens.
