dcterms.abstractThe advancements in customizable, adaptive unmanned surface vessels (USV) have contributed to the increasing presence of USVs completing maritime site characterizations with commercial off-the-shelf (COTS) sensors such as side-scan sonars and sub-bottom profilers rather than scientific divers. USVs accomplish this through a combination of hardware and software capabilities such as highly precise positioning systems, inertial measurement units, and a semi-centralized operating system. This allows for objectively and functionally better performance in the form of human-assisted waypoint navigation, semi-autonomous deployment, and minimization of errors associated with uncontrollable perturbations like wind and ocean current. This thesis aims to present recommendations for the electromechanical design and integration of COTS sensors onboard a capable USV for the purposes of site characterization such that data collected in real-time may precisely characterize the environment and be rapidly tuned for optimal analysis remotely. An initial evaluation of various mitigation or suppression efforts yielded marginal improvement to the distortion within sonar images. Further mitigation efforts yielded significant improvement in sonar images as additional techniques were applied to COTS sensing systems attempting to interoperate with low-cost USVs. The resulting contribution of this thesis is an effort to performance yield that quantifies non-invasive noise and attenuation mitigation techniques for COTS sensing systems aboard a low-cost marine platform.
