ACOUSTIC-OPTICAL RECEIVER Russian patent published in 2008 - IPC H04B10/06 

FIELD: radio-electronics, possible use for receiving, direction-finding, spectral analysis and detection of complex signals with phase manipulation.

SUBSTANCE: acoustic-optical receiver contains first, second and third antennas, frequency transformer, first and second heterodynes, first, second and third mixers, first, second and third amplifiers of intermediate frequency, first, second, third, fourth and fifth multipliers, first, second, third and fourth narrowband filters, first and second correlators, first and second threshold blocks, first, second and third keys, first and second phase detectors, first and second registration blocks, low frequency filter, laser, collimator, first, second and third Bragg cells, first and second lenses, first and second matrices of photo-detectors.

EFFECT: expanded functional capabilities of acoustic-optical receiver due to precise and unambiguous direction-finding of phase-manipulated signals source in two planes at stable frequency, equal to difference of heterodyne frequencies f_h2-f_h1=2f_up.
