SWellEX Experiment Planning and Data Analysis.

Abstract

SWellEx-3 (Shallow Water evaluation cell Experiment #3), was carried out in July 1994 west of Point Loma in approximately 200 m water. A MPL 64-element vertical array was deployed from the R/P FLIP and the NRaD SWSS (Shallow Water Sensor String) horizontal line array was co-deployed 500 m to the east and cabled back to shore. During SWellEx-3, several source tow events were conducted which included radial tracks (both range independent as well as cross slope), arc (constant range but varying bathymetry) tracks, and CPA (closest point of approach) tracks. These events were designed to investigate the performance of matched field processing (MFP) in shallow water as well as to provide simultaneous data for intercomparison of vertical and horizontal line array processing. Vertical array, conventional (Bartlett), MFP has proven to be surprisingly robust to bathymetry mismatch. Horizontal array MFP near endfire was able to localize the source in range and depth even though the array aperture was relatively modest (300 m).
