Claims: What is claimed is:

1. 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.

2. The radar decoy of claim 1 wherein said plastic balloon comprises a cylindrical balloon made from a dimensionally stable plastic material.

3. The radar decoy of claim 2 wherein said printed circuit radiators comprise printed circuit dipoles.

4. 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.
