Study of the Phase Characteristics of Echo Signals for Vertical Sounding of Water with Signals with Linear Frequency Modulation

摘要

We study the phase characteristics of echo signals during vertical acoustic sounding of a water medium with narrowly directed emission. We experimentally demonstrate the possibility of measuring the dependence of the phase of echo signals on the delay for a probe signal with linear frequency modulation. We substantiate the possibility of remote determination of sound velocity variations in water.
