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.

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.
