Abstract:

The detection performance of low spectral level, broadband signals from a submerged acoustic source in the presence of strong surface interference is described and illustrated with examples obtained in the May 1996 shallow water evaluation cell experiment (SWellEx-96). The experiment was carried out west of Point Loma in 200-m water of complex bathymetry. A vertical line array (VLA) was deployed next to an identical line array tilted at 45 deg. The detection performance of each of the arrays with linear and adaptive matched-field processing is measured and compared. [Work sponsored by Office of Naval Research, Code 321(US).]
