FIELD: radio engineering, communication.SUBSTANCE: device includes two quadrature channels, outputs of which are connected through corresponding squaring devices to inputs of an output adder. Each of the quadrature channels consists of a phase detector, the output of which is connected to the input of a two-cycle detector and to the input of a first delay line, the input, output and leads of which are connected through corresponding phase changers to inputs of one adder, and the input, output and leads of the second delay line are connected through corresponding phase changers to inputs of the other adder. Each quadrature channel consists of a limiter connected between the output of the two-cycle detector and the input of the second delay line, and a functional amplifier connected between the output of the second adder and the input of the first adder.EFFECT: high sensitivity in discontinuous passive jamming conditions.2 dwg |
