Abstract: The towed multi-band radar decoy or target is a collapsible, airstream-inflatable device intended to be used for providing gunnery practice or electronic countermeasure protection for aircraft against radars and radar-guided missiles by being towed on a line behind the aircraft and offering a more attractive radar target than the aircraft for the radar or radar guided missile to track and home on. The decoy or target is collapsible, so that many can be stored in a small space, and can be deployed while an aircraft is airborne. The decoy is comprised of a sleeve of radar-transparent fabric having a tapered cylindrical shape and an open mouth at a narrow end, and clusters of orthogonal trihedral corners formed from flat conductive surfaces fixed inside and to said sleeve which can be folded and collapsed into a small space, and once inflated, for providing a radar reflective signature which exceeds that of a towing aircraft over predetermined angular aspects.
