Patent ID: 8830112

Claim:
A method of radar jamming comprising the combination of steps of: transmitting a first signal of suitable frequency content and power level for radar jamming from a signal radiator adjacent the trailing end of an elongate transmission line towed by an aircraft in which said first signal is a noise signal transmitted at a predetermined power level; concurrently transmitting a second signal of noise content from a transmitting location proximate the aircraft; receiving a transmitted radar signal at such aircraft; selectively modifying the transmission of said second signal so as to reduce its output level at times determined by the receipt of a transmitted radar signal so that the composite signal energy of the second signal and a reflection by the body of such aircraft of a transmitted radar signal is substantially uniform during the time of the reflected radar signal and such composite signal energy is superimposed by said first signal radiated from said radiator towed by the aircraft; and wherein said predetermined power level of said first signal is selected to be substantially greater than an unreduced normal output level of said second signal so that the combined first and second signals have an apparent point of origin at a position along said transmission line that lies closer to said signal radiator than to the body of the aircraft.
