METHOD OF DETERMINATION OF DISTANCE TO BOTTOM AND DEVICE FOR ITS REALIZATION Russian patent published in 1995 - IPC

Abstract RU 2042960 C1

FIELD: hydroacoustics. SUBSTANCE: correlation time delay between radiated and reflected signals is determined by minimum ratio of product of cross-correlation function of delayed signal and Gilbert conversion of reflected signal by cross-correlation function of delayed radiated and reflected signals to difference of squares of data of cross-correlation functions respectively. EFFECT: enhanced efficiency. 3 cl
