ACOUSTO-OPTIC RECEIVER

FIELD: radio engineering. ^ SUBSTANCE: invention may be used for detection of radio stations airing, which have pseudorandom operational frequency readjustment and determination of the used frequency network. Acousto-optic receiver contains antennae (1), frequency converter (2), laser (8), collimator (9), Bregg cell (10), lens (11), photo detector matrix (12) and recorder (13). Frequency converter (2) is multi-channel, consisting of m lines and n columns. Each line contains narrow-band filter (3ij) and (n-1) links. Each link is comprised of heterodyne (4 ij), mixer (5ij) and amplifier (6ij) of intermediate frequency. Intermediate frequency amplifier outputs of column (n-1) are connected with piezo-electric converter of Bregg cell through logic element OR. ^ EFFECT: possibility of simultaneous and parallel detection and receipt of several short-term signals appearing at different frequencies and belonging to controlled radio station with pseudorandom operational frequency readjustment. ^ 3 dwg
