Abstract
A rf decoy for use with rf repeater devices, transponders, noise jammers and other jamming devices. The decoy is adapted to be towed behind an aircraft using a tow line which incorporates a fiber optic link through which signals are transmitted. The device is excited through rf energy which is modulated on a laser carrier and transmitted through the fiber optic link. While the principal application is to repeaters which are towed behind an aircraft, the invention has utility in free-falling and forward fired transmitters as well as land and sea based vehicles.
Claims3
In a radar decoy system for protecting a vehicle against hostile radar detection by means of a decoy device which is physically interconnected in spaced relation relative to the protected vehicle by a flexible cable means, the improvement comprising:
- an rf receiving means on said vehicle for receiving hostile signals, an rf exciting means on said vehicle responsive to said received signals, an rf transmitting means on said decoy device, and means interconnecting said exciting means and said transmitting means, said last-mentioned means including a laser modulator, a laser transmitter receiving the output of said modulator, a fiber-optic link incorporated into said flexible cable means receiving the output of said laser transmitter, and a laser receiver on said decoy device interconnected to said fiber-optic link and receiving transmitted signals therefrom, said laser receiver being interconnected to said transmitter means.
