Acoustic Sensing and Tracking from Networked Autonomous Platforms

The goals of this work are varied, but will focus on the assessment of acoustic vector sensor data collection from autonomous platforms, and options for data exfiltration. Specific goals also include effective demonstrations of tasking autonomous UUVs to perform data collection runs remotely (both while surfaced and submerged), confirming UUV performance with acoustic sensor attachment, demonstrating communication performance between autonomous UUVs and USVs equipped with underwater acoustic modems, investigations of standard and adaptive signal processing of acoustic vector sensor data for determining source direction, evaluation of acoustic vector sensor processing gains when equipping UUVs with secondary vector sensors, integration of on-board processing of acoustic vector sensor data, and development of low-power, small form-factor science computer for data acquisition and processing that can be deployed on alternative autonomous systems.
