Abstract: Apparatus for detecting any signal occurring within a wide bandwidth and playing it with a signal-to-noise performance substantially equal to that of a receiver of optimum bandwidth for that signal. The apparatus essentially comprises a special purpose cathode ray tube that functions as a plurality of different detectors that can self-optimize to detect any signal within a wide bandwidth by means of the interactions between the received signals and an electron beam having a wide range of electron velocities and traveling in a zig-zag path in the cathode ray tube.

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.
