Collect bistatic scattering data around spherical and aspect-dependent targets in realistic harbor environments.

Demonstrate chip scale atomic clock-based precision timed data acquisition in the field.

Demonstrate autonomy, signal processing, and machine learning methods developed in simulation for classification of seabed targets using bistatic scattering amplitudes.

Experiment Assets:

AUV Unicorn with shallow water active acoustic payload and 16-element nose array.

Lubell acoustic source with time-synchronization (Mass Bay Experiment).


GOATS'14 consisted of two experiments looking at bistatic scattering from symmetric and aspect dependent target using the AUV Unicorn. The first experiment, in May 2014, was a part of BayEx'14 effort in Panama City, FL. The second in November 2014 was conducted in Massachusetts Bay. For both experiments, a time-synchronized acoustic source insonified a target field, and the AUV Unicorn collected acoustic data on a hydrophone nose array. The data was processed to estimate target scattering amplitudes. The resulting target scattering maps were compared to simulation results and used to test a target classification methodology.
