Abstract: A crossed skirt antiradar screen structure for a space vehicle, such as an orbiting satellite vehicle, having members projecting laterally from the main vehicle body. The screen structure includes multiple primary and auxiliary radar screens having electrically conductive skirts at least partially enclosing the vehicle body and the projecting members in a manner such that the screens cooperate to control the radar cross-section and signature of the entire vehicle. According to an important feature of the invention, the several radar screens are so shaped and arranged that all interior corners defined by the screen skirts have oblique angles which preclude retroreflection of an illuminating radar beam from a ground based radar detection system.

Abstract: A controlled scintillation rate decoy having microwave reflectors for reflecting incident radar energy in a manner to provide the decoy with a selected radar cross-section, and variable electrical impedance control means connected in electrical circuit with the reflectors for controlling the scintillation magnitude or scintillation rate of the decoy.
