FIELD: radio, communication.SUBSTANCE: device comprises two quadrature phase detectors, a cosine-sine generator, four integrators, three square-law detectors, an adder, a threshold unit, three units of subtraction, two multipliers interconnected in a certain manner.EFFECT: reduction of threshold signal-to-noise ratio at the input of the threshold unit of the panoramic receiver detector which determines its sensitivity at given values of probability of detection and false alarm, which corresponds to an increase in the detection range of the radio-frequency radiation source and reduction of analysis time of electronic environment in a given analyzed frequency band for the a priori unknown crowding of the RFS frequency band.3 dwg |
