METHOD FOR DETERMINATION OF SOUND SOURCE BEARING Russian patent published in 2008 - IPC G01S3/80 G01S3/803 G01S5/20 

FIELD: acoustic direction finders (base points of perspective automatic sound-ranging complexes, applicable for determining the bearing of the sound source and topographic co-ordinates of this sound source.

SUBSTANCE: the basic wind parameters in the ground surface layer of the atmosphere and the air temperature in this layer are measured, the parameters, standard characteristics of the directivity of the sound detector line groups are computed, the sound detectors are disposed in a definite manner so as to receive the acoustic signals, which then are transformed to electric signals, processed in a special manner, the maximum amplitudes of voltages of these signals at outputs 1 and 2 of the signal processing channels are automatically measured, the difference of the maximum voltage amplitude at output 1 of the signal processing channels and the maximum voltage amplitude at output 2 of the signal processing channels is calculated, the sum of these amplitudes, relation of this difference to their sum are calculated, and the bearing of the sound source is automatically determined.

EFFECT: enhanced accuracy of direction finding of the sound source and reduced time of bearing finding.
