High Resolution Sea Surface Mapping Radar System

Abstract

This Phase I SBIR Final Report addresses the development of a novel rapid scanning radar interferometer designed to map the surface topography of the ocean surface within several hundred meters of an unmanned surface vehicle (USV). A system capable of mapping local sea conditions can help stabilize a USV in high seas by providing input data to an adaptive vessel control system. The proposed interferometer will operate in much the same way as conventional marine radar, enclosing a rotating pair of fan beam antennas in a radome near the top of the USV to provide 360-degree coverage. The system described in this report is based on proven radar interferometry technology developed for oceanographic research applications. As part of this contract we developed a software simulation of the mapping process, accounting for realistic sea states and expected radar parameters. Based on the results of these simulations we designed a prototype system, including the radar, data system, and auxiliary sensors and interfaces necessary to implement real-time stabilization of a USV.
