GEAR SIMULATING TARGETS Russian patent published in 1997 - IPC

FIELD: SHF equipment, testing and checking of airborne radar stations, for instance, of aircraft interception and aiming radars. SUBSTANCE: gear simulating targets has echo-free chamber, reflector placed by one of face walls of echo-free chamber, radiator installed in focus of reflector and connected to output of simulator of echo signals of target, antenna of controlled object, for example, of airborne radar placed into hole in wall opposite to face wall of echo-free chamber and tested radar. characteristic feature of gear consists in manufacture of reflector in the form of truncated sphere-parabolic mirror which profile in horizontal planes resents arcs of circle and radiator or row of radiators for simultaneous emulation of several targets which are positioned on half-radius of arc of circle formed by focuses of parabolas. Each radiator is connected to its simulator of echo signal. Reflector is mounted in near zone of antenna of checked radar and is oriented with respect to this antenna so that its vertical axis passes through center of radar antenna. EFFECT: enhanced operational efficiency. 2 dwg
