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.
