Algorithm for Determining the Coordinates of a Hydroacoustic Source Using the Correlation Function of Its Signal

Abstract

Abstract—An algorithm for determining the coordinates (distance and depth) of a broadband signal source has been developed, which uses as the input data the parameters of the maxima in the signal correlation function at the output of the receiving hydroacoustic array and takes into account the number of negative factors affecting the algorithm’s accuracy when operating in real conditions. Simulation is used to demonstrate the algorithm’s applicability conditions and obtain the dependences of the accuracy in estimating the coordinates of a signal source on the number of detected maxima in the correlation function, on the signal-to-noise ratio at the output of the receiving array, and on the accuracy in measuring the vertical sound velocity distribution in the observation area.
