ABSTRACT:
A device to be used as a guidance system for sonar or radar or similar transmissions in which a dihedral reflector is used in association with part of the earth's surface (land or sea) whereby a trihedral reflector results for such transmissions in which spurious signals are avoided because the earth forms one of the reflective surfaces to thereby remove spurious signals which could otherwise occur with a normal trihedral reflector.
