AIRBORNE RESPONDER Russian patent published in 2003 - IPC

FIELD: radiolocation. SUBSTANCE: invention can find use in devices processing interrogation signals and radiation of response signal in direction from which most powerful interrogation signal was received. Technical result of invention lies in raised probability of making correct decision by radiation of response signal in direction from which most powerful interrogation signal was received. To achieve this technical result mix of digital circuit of automatic noise gain control is supplemented with digital line transmitting data on coarseness of sensitivity of receiver. Information on condition of attenuators of receiving channels at moment of receipt of interrogation signal is taken into account when amplitudes of interrogation signal are compared. EFFECT: raised probability of making correct decision. 4 dwg
