US Patent 7336216 Parachuted radar decoy

A radar decoy having radar reflectors disposed in the interior of the inflated canopy of a descending parachute as a first set of four corner reflectors, and a second set of corner reflectors disposed on the exterior of the canopy integral with the first set of corner reflectors, to form an octahedron of eight corner reflectors. The radar decoy is pliable and folded with the parachute for stowage in the interior of a canister. When loaded on a vehicle flying in a trajectory, the canister may open at a point P on the trajectory, to release the parachute, and thereby deploy the radar decoy to become operative.
