Patent ID: 6872960

Claim:
A system for focusing electromagnetic energy on a target having a nature, functionality, purpose, operational state and threat, the system comprising: first means for directing a pilot beam of electromagnetic energy toward the target to covertly obtain information from the target; second means for receiving a spatially and temporally dependent electromagnetic field having phase, frequency, amplitude, and polarization characteristics, wherein the electromagnetic field corresponds to a reflection of said pilot beam from the target which includes detected information from the target; third means for analyzing the received electromagnetic field from the target to determine, from the received electromagnetic field, information that is indicative of at least one of: the nature of the target, the functionality of the target, the purpose of the target, the operational state of the target and the threat of the target and in response to the information for providing data which is indicative of at least one of: the nature of the target, the functionality of the target, the purpose of the target, the operational state of the target and the threat of the target; and fourth means for receiving the data from said third means and in response to said data for providing modulated information back to the target and wherein said fourth means is adapted to modulate the output beam by changing at least one of a phase characteristic, a frequency characteristic, an amplitude characteristic, a polarization characteristic and a carrier frequency wavelength characteristic and wherein the modulated output beam is predistorted to compensate for distortions, phase noise and amplitude noise in said received electromagnetic field.
