FIELD: hydroacoustics. SUBSTANCE: composite signal is radiated which consists of inverse pair of signals shifted at hyperbolic frequency modulation which ensures more accurate determination of time delay which is not measured but corresponds to maximum magnitude of cross-correlation function between radiated and reflected signals. EFFECT: enhanced accuracy of measurement. 2 cl, 5 dwg
