Abstract

A method for the acoustic noise mapping of a shallow ocean using a tomographic approach is presented. The output of a planar array of hydrophones in the ocean is expressed as a weighted line integral of the acoustic field. A set of measurements of the array output for different steering directions and several array locations can be inverted using an algebraic reconstruction technique to reconstruct the acoustic field. The tomographic approach yields fairly good results even though no deconvolution of the array output was done and a small number of arrays was used.
