Abstract
A technique has been developed to estimate the three dimensional character of the undersea ambient noise field from beam noise data acquired by a horizontal line array. Results are presented wherein measured beam noise data for several array headings and knowledge of the array's beam response patterns were used to estimate the 3-D noise field.
