FIELD: instruments for radio engineering. SUBSTANCE: device has first, second and third antennas, first, second and third mixers, location unit, first and second heterodynes, fourth multiplier, first narrow-band filter, first, second and third intermediate frequency amplifiers, detector, frequency multiplier by factor of eight, first and second detectors of spectrum width, comparison unit, threshold gate, delay line, fifth and sixth multipliers, second and third narrow-band filters, laser, collimator, fifth, sixth, seventh, eighth, first, second, third, fourth, ninth, tenth and eleventh Brag cells, fifth, sixth, seventh, eighth lenses, first, second, third and fourth apertures, optical gate, fifth photodetector, sixth photodetector, first, second, third, fourth, seventh and eighth photodetectors, acoustic-optical frequency discriminator, acoustic-optical phase discriminator, first, second, third and fourth indication units, third and fourth indication units, first and second shutters, first and second reading registers, first and second threshold gates, first, fourth and fifth gates, first and second phase detectors, fifth and sixth recording units, first, second and third multipliers, first, second and third band-pass filters, switch, third, sixth, second and seventh gates, seventh, first and eighth recording units, first and second mutual tuning units. Device may be used for measuring frequency and direction of received signals, as well as for spectral analysis of complex signal and for detection of their modulation. EFFECT: increased functional capabilities due to search of complex signals in given range, possibility of their detection and finding direction to source of complex signals in two planes. |
