ABSTRACT:
In a holographic surveillance system (10) for near real-time imaging of a target (15), a source of RF radiation directs a non-amplified reference beam of pulsed coherent RF electromagnetic radiation toward a target. An array of antennas (31) receives a reflected beam from the target together with a component of the reference beam so as to produce a signal representative of phase and amplitude data of received energy, and a processor (20) processes the signals so as to produce a holographic image for display on a display device coupled to the processor.
