FACILITY FOR INPUT OF SHF SIGNALS OF TARGET AND NOISE SIMULATOR IN MIX OF AIRBORNE RADAR WITH COMPENSATION JAMPROOF CHANNEL Russian patent published in 2003 - IPC

FIELD: radiolocation, built-in airborne radars with compensation jamproof channel. SUBSTANCE: facility for input of SHF signals of target and noise simulator in mix of airborne radar has transmission line for connection to SHF simulator, attenuator and unit for connection to SHF input of airborne radar connected in series. The latter incorporates two waveguide directional couplers and reference generator of SHF noise. Directivity of coupling of SHF signals of target and noise simulator and of reference generator of SHF noise is set such that approximate equality of signals of SHF simulator across input of main radar antenna and part of same signals across input of receiver of compensation jamproof channel of receiver of airborne radar to which SHF noise from generator of SHF noise is fed is provided. EFFECT: diminished shadowing of main antenna of airborne radar and ensured capability of calibration of input SHF signal of target and noise simulator with use of reference generator of SHF noise. 1 dwg
