Exploiting Hydrophone Flow Noise Spatiotemporal Correlation for Enhanced Signal Detection
Abstract
The objective of this research effort is to demonstrate the potential effectiveness of compact array devices for undersea applications. The technical approach is based on implementing existing models of wall-bounded, turbulence-created pressure fluctuations to generate synthetic measurement time series and then applying adaptive signal processing algorithms to these time series to assess the potential performance gains of an underwater compact array device. If successful, the research effort will provide a pathway forward for significant enhancement of source signal detection and bearing-of-arrival estimation capabilities with potentially much smaller (lower total sensor count) array systems and at much greater sensor velocities.
