Bistatic Synthetic Aperture Sonar Measurements and Preliminary Analysis

Abstract

As part of the sediment acoustics experiment-2004 (SAX04), bistatic synthetic aperture sonar (SAS) measurements were made. The Applied Physics Laboratory (APL-UW) rail/tower system was used to receive signals emitted by either the Naval Surface Warfare Center-Panama City (NSWC-PC) tower with a parametric source or a separate APL-UW tower with an omnidirectional source. For the parametric source, the relevant frequency bands are 1-5 and 60-65 kHz. The omnidirectional source emitted a shore 20 kHz sine wave burst. A brief description of the measurement geometry will given, and the time-domain imaging algorithm will be outlined. The NAVSEA funding document title for N00014-02-G-0460 is "SAX04 Bistatic Measurements of VLF Bottom Reverberation and Target Strength."
