FIELD: physics, radio.
SUBSTANCE: invention refers to radio communication and can be applied in broadband pseudorandom signal (PRS) systems. The detector contains two quadrature channels, π/2 phase shifter, heterodynes, three adders, threshold device. Each quadrature channel contains multiplier, band-pass filter, analogue-to-digital converter, digital matched filter, integrator, peak signal detector, selector, averager and two quadrators.
EFFECT: stable PRS detection in great frequency mismatch of received signals concerning reference frequency of the detector and in weak energy profile of radio line.
