The SeaSearcher system extends capabilities well beyond what is available today in the area of sub-bottom imaging. While sub-bottom imaging has existed for years to identify course strata and general layer density, the technology to perform high-resolution 3D imaging below the sea-bottom in real-time on an autonomous vehicle has not. The SeaSearcher flies like a ray manually or autonomous just a few feet off of the sea-bottom and uses an array of specialized sensors to develop a 3D image of what is on and below the sea-bottom including its likely composition attributes. These images are fed back to the command vessel and/or command center via a surface buoy and wireless link to be processed using proprietary Automatic Target Discrimination software which looks for the attributes of our targets of interest.
