Abstract
A method for identifying position of acoustic source proximate sediments below the bottom of a body of water includes deploying a plurality of arrays of acoustic sensors on the bottom of the body of water. Each array includes a plurality of lines of acoustic sensors disposed in a substantially radial pattern. The arrays have a center to center distance therebetween of about twice a diameter of each of the arrays. Signals are detected from each of the sensors for a selected time period. A direction of the acoustic source with respect to each of the arrays is determined by steering a response of the sensors in each array. A range of the acoustic source is determined using the determined directions.
