Estimation of Sediment Properties Using Air Launched Sonobuoys
Abstract
Modal dispersion data are used in inversion schemes that estimate sediment properties in range independent and range-dependent environments. The experimental scenario for the use of air launched sonobuoys to extract information about the sediment properties in the area covered by the sonobuoys is to have one of the sonobuoys broadcast a broad band signal with a large set of buoys receive these signals. These receiving sonobuoys will be dispersed over a wide area. In such an experimental set up the data acquired by the sonobuoys is used to estimate the sediment properties in the area covered by the sonobuoys. In March 2011, an experiment termed MOMAXV was conducted off the New Jersey coast. In this experiment broad band signals were broadcast from a ship carrying the source. The ship moved to discrete locations around a small set of free-floating buoys. This mimicked the situation where we have a near stationary sonobuoy with a source transmitting a broadband signals and a network of freely floating sonobuoys acquiring the transmitted signals. The objective of the current work is to analyze the data collected during the experiment and estimate the sediment properties of the region between the ship positions and the location of the sonobuoys.
