VLF Source Localization with a Freely Drifting Sensor Array
2007
Chen, George C.
Source localization and tracking capability of the freely drifting Swallow float volumetric array is demonstrated with matched-field processing (MFP) technique using data collected during the 1989 Swallow float experiment conducted in the Northwest Pacific, Marine Physical Laboratory's set of nine freely drifting, infrasonic sensors, capable of recording ocean ambient noise in the 1- to 25-Hz range, was deployed to span the water column of 4100-m depth, with horizontal aperture on the order of 5 km. Even though the floats were drifting, their positions were determined with the 8-kHz internal navigation system and a postprocessing least-squares-based localization procedure
