Estimation of the time delay of hydroacoustic signals for passive location of underwater objects

A. Makar
Naval University, Institute of Navigation and Hydrography

In this paper a method of time delay estimation of acoustic
signals radiated in water has been shown. The source of these signals is a
moving ship. The gradient adaptive method of minimizing the error has been used.
An algorithm of estimation using this method and the results of estimation the
real signals radiated by a moving ship have been presented.
Keywords: estimation; time delay; underwater navigation
