ACOUSTOOPTICAL RECEIVER Russian patent published in 2012 - IPC H04B10/06 

FIELD: radio engineering.

SUBSTANCE: acoustooptical receiver comprises three receiving antennas 1, 2 and 10, a frequency converter 3, heterodynes 4 and 5, mixers 6, 7 and 10.1, amplifiers 8, 8 and 11 of intermediate frequency, Bragg cells 12, 13, 14, 15, 22, 30 and 31, keys 16, 19, 38, 39, 46 and 47, lenses 17, 18, 23, 32, 27 and 28, a laser 20, a collimator 21, matrices of photodetectors 24, 29, 33 and 34, gates 35 and 43, reading registers 36 and 44, threshold units 37 and 45, registration units 40, 41, 48 and 49, mutual alignment units 42 and 50. Receiving antennas form a geometric right angle, in the top of which there is the first receiving antenna, common for metering bases formed by the second and third receiving antennas in azimuthal and elevation planes simultaneously.

EFFECT: invention provides for accurate and unambiguous direction finding of a source of complex signal radiation with phase manipulation in two planes.
