Abstract
A passive EW radar decoy capable of simulating relatively large targets s as naval ships. The decoy comprises a cylindrical, dimensionally stable plastic balloon having uniformly distributed on the surface thereof a Van Atta array of printed circuit radiators. The radiators in the array are disposed in a selectively predetermined geometric configuration such that incident energy from a remote source is reradiated by the array in the direction of the remote source. The decoy comprises a low-cost, light-weight, relatively simple structure that can be easily stored and rapidly deployed and released.
Claims4
A passive, high-cross section radar decoy comprising:
- a plastic balloon having a selectively predetermined volume,
- said balloon having uniformly distributed on the surface thereof a plurality of printed circuit radiators,
- said radiators being disposed and arranged in a Van Atta array configuration whereby radiant energy from a distant source received by said radiators is reradiated in the direction of the source.
A passive, low-cost, light-weight radar decoy comprising:
- a cylindrical, dimensionally stable, plastic balloon,
- said balloon having a selectively predetermined volume whereby the echoing area of said decoy substantially simulates a given radar target,
- a plurality of printed circuit dipoles,
- said dipoles being uniformly distributed on the surface of said cylindrical balloon,
- said dispoles being disposed and arranged in a Van Atta array configuration whereby incident radiation from a distant source is reradiated in the direction of the source.
