Abstract:
1. A system that exploits the Bragg Effect to identify at least one pattern within at least one pre-specified geographic area, comprising: an array of transceiver stations, each said station having at least one antenna, wherein said array is remotely located from said pre-specified geographic area; at least one processor in operable communication with said array; and at least one display in operable communication with at least said processor, wherein each said transceiver station illuminates at least one said pre-specified geographic area with electromagnetic energy at a carrier frequency that may generate a Bragg resonance as a result of said carrier frequency being swept in frequency over a pre-specified band within a pre-specified time interval, and wherein if an orderly array of objects populate said pre-specified geographic area, said at least one transceiver station receives at least one reflection of electromagnetic energy from at least one object in said orderly array of objects that is coherent with a reflection of energy received from other objects in said orderly array of objects reflecting energy at said carrier frequency that generates a Bragg resonance.
