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.
