Deep Vector Sensor System

The Phase I program is directed at defining a buoy configuration that will capture the improved signal-to-noise ratios of surface or near-surface targets-of-interest when the acoustic sensor is located below the critical depth and as close to the ocean bottom as possible, capitalizing on the Reliable Acoustic Path. The overall buoy configuration options include a free-floating buoy and a buoy with an on-the-bottom sensor subsystem. In addition, the Phase I effort will include optimizing each subsystem and establishing a reliable packaging and deployment approach. Critical subsystems being optimized include the vector acoustic sensor and the subsurface-to-surface data link. Compatibility with the new proposed sonobuoy RF link utilizing a CPGFSK (Continuous Phase Gaussian Frequency Shift Keying) waveform is also included.
