ABSTRACT:
A compact electromagnetic antenna pattern range includes a planar reflector which is controllable between a reflective condition and a transmissive condition. The controllable reflector is placed parallel to a second planar reflector, and a pulse of electromagnetic energy is injected into the space between the reflectors, propagating toward one of the reflectors. After a number of re-reflections, the controllable reflector is rendered transmissive and a substantially planar wavefront is made available for application to the antenna under test.
