ABSTRACT:
A microwave radar reflector includes three, substantially planar networks whose reflectivity or transmissivity may be controlled. The three networks are arranged as a trihedron with an open angle. An additional network, whose reflectivity or transmissivity may be separately controlled, is located at said open angle of the trihedron. With the additional network controlled to be transmissive and the other networks having their characteristic modulated between reflective and transmissive, the reflector will return a modulated message when the reflector is illuminated.
