PORTABLE PASSIVE REFLECTOR

摘要

A portable passive reflector that utilizes a Luneberg lens to focus upon a diode array positioned about the focal region of the lens, an interrogating signal eminating from a predetermined direction. A reflecting plate is mounted behind the diode array a distance equivalent to multiples of a quarter wavelength of the interrogating signal. By selectively pulsing the diode array, the effective cross section of the reflector as seen by the interrogating radar is varied thus modulating the reflected signal.
