- угловая координата n-го гидрофона базы,
n = l,2,....N, N - число гидрофонов базы;
ϑn - кумулятивная фаза на n-ном гидрофоне базы относительно фазы на первом гидрофоне, относительно которого отсчитываются углы φn, θo, вычисляемая по формуле
ϑn= (ϑn-ϑn-1)+(ϑn-1-ϑn-2)+...(ϑ2-ϑ1),
причем первым гидрофоном считают лежащий на направлении максимума сигнала.1. The method of determining the bearing to the radiation source, which consists in the generation and radiation of a harmonic signal source frequency receiving an acoustic signal by a set of N hydrophones forming a horizontal measuring base oriented in the horizontal plane, isolating the quadrature components of the complex envelope of the received acoustic signals, and measuring the phase of the received acoustic signals, characterized in that the circular measuring base is collected from at least eight hydrophones, received by the base hydrophones are pre-phased into N directions passing through the center of the base and each of the N hydrophones determines the direction, respectively vuyuschee maximum signal and a hydrophone, lying in this direction, and bearing to the source of the local coordinate system associated with a circular base, determined by the formula
Where
is the angular coordinate of the nth base hydrophone,
n = l, 2, .... N, N is the number of base hydrophones;
ϑ n is the cumulative phase at the nth base hydrophone relative to the phase at the first hydrophone, relative to which the angles φ n , θ o are calculated, calculated by the formula
ϑ n = (ϑ n -ϑ n-1 ) + (ϑ n-1 -ϑ n-2 ) + ... (ϑ 2 -ϑ 1 ),
and the first hydrophone is considered lying on the direction of the maximum signal.
