Abstract
A method for producing a spherical radar reflector containing triple reflectors and composed of identically shaped eighths of a sphere is described. The eighths of the sphere consist of foam material and their plane surface, which are in contact with each other, are constructed to be reflecting. The eighths of the sphere are individually expansion molded in appropriate molds and the plane surfaces of the eighths of the sphere are covered with material reflecting radar rays. This material can consist of metal foils or can be a mixture of an adhesive and of metal particles which are uniformly distributed in the adhesive.
Claims7
A process for producing a spherical radar reflector, comprising:
- expansion molding eight individual and identically-shaped eighths of a sphere in a mold having smooth sides, each eighth of a sphere being made of foam material and having three mutually perpendicular plane surfaces;
- bonding a material which reflects radar rays to the plane surfaces of each eighth of a sphere;
- and bonding the eighths of a sphere together to form the spherical radar reflector.
A process for producing a spherical reflector, comprising:
- expansion molding eight individual and identically-shaped eighths of a sphere in a mold having smooth sides, each eighth of a sphere being made of foam material and having three mutually perpendicular plane surfaces;
- bonding a material which reflects radar rays to the plane surfaces of each eighth of a sphere;
- and
- bonding the eighths of a sphere together to form the spherical radar reflector;
- wherein the step of bonding a material which reflects radar rays comprises applying an adhesive having metallic particles and another electrically conductive metal uniformly distributed therein to the plane surfaces of each eighth of a sphere so as to bond said eighths of a sphere together.
