AMPLITUDE DIRECTION FINDER OF ACTIVE JAMMING RADIATORS Russian patent published in 2004 - IPC

FIELD: radio detection and ranging, applicable for determination of angular co - ordinates of active jamming radiators. SUBSTANCE: the amplitude direction finder has a series-connected antenna system and a receiver, as well as a storage unit and an averaging unit connected to the inputs of a comparison unit, the first and second maximum selection units, antenna angle-of-turn transmitter, three co-ordinate take-off units, the second storage unit, valve and a master oscillator are introduced in it, the signal input of the first maximum selection unit is connected to the receiver output and its signal output - to the inputs of the first storage unit and comparison unit, the control output is connected to the control input of the first co- ordinate take-off unit, whose input is connected to the output of the antenna angular position transmitter, and the output - to the signal input of the second storage unit, whose output is connected to the input of the second co-ordinate take-off unit, connected to the output of the second co-ordinate take-off unit is the input of the third co-ordinate take-off unit, whose output serves as the direction finder output, the master oscillator output is connected to the synchronizing inputs of the first and second storage units and the control input of the first maximum selection unit, the output of the comparison unit is connected to the control inputs of the valve, second maximum selection unit and third co-ordinate take-off unit, and the signal input of the valve is connected to the output of the first storage unit, each maximum selection unit contains the first and second access and storage units, second comparison unit, second master oscillator, AND gate and OR gate, the input of the first access and storage unit is connected to one of the inputs of the second comparison unit and serves as the signal input of the maximum selection unit, the output of the first access and storage unit is connected to the second input of the second comparison unit and to the input of the second access and storage unit, the master oscillator is connected to the input of the AND gate connected to whose second input is the output of the second comparison unit, the output of the AND gate is connected to the input of the OR gate, whose second input is combined with the control input of the second access and storage unit and serves as the control input of the maximum selection unit, the output of the OR gate is connected to the control input of the first access and storage unit and serves as the control output of the maximum selection unit, the output of the second access and storage unit serves as the signal output of the maximum selection unit. EFFECT: eliminated false bearings at a direction finding of non-stationary jamming radiators. 7 dwg
