Micromachined Directional Hydrophones
Abstract
The long-term goal of this investigation was to develop a high-performance, miniature, directional hydrophone to either replace existing omnidirectional sensors or to greatly increase the number of directional sensors in deployable surveillance and tactical ASW and USW systems. Increased directionality yields improved signal detection, improved noise discrimination, and improved classification ability. The technical objective was to develop a low frequency, miniature, directional hydrophone element by exploiting emerging silicon microfabrication technology (MicroElectroMechanical Systems or MEMS).
