FIELD: sea navigation techniques. SUBSTANCE: method includes addition to the known method of measuring distance to sea bottom (e.g., sonic finder) of search of correlation time delay by determination of square of coefficient of mutual correlation function, square of conversion of gilbert from coefficient of mutual correlation function of reflected and sounding signals and their comparison. EFFECT: higher accuracy of distance determination. 1 dwg
