Littoral Sensors for Naval Special Forces Navy STTR FY2005 Sol No.: Navy STTR FY2005 Topic No.: N05-T027 Topic Title: Littoral Sensors for Naval Special Forces Proposal No.: N054-027-0329 Firm: Continental Controls and Design, Inc. 20252 Bancroft Circle Huntington Beach, California 92646-4722 Contact: Jim Hynes Phone: (714) 964-6553 Abstract: We propose to develop a littoral sensor which can map bottom properties in Very Shallow Water to help preparation for operations at the beach head. We are already in the second phase of development on a low cost directional wave buoy which is about the size of a small flashlight. In this project, with the assistance of Cal Poly SLO, we will add a thermistor to monitor water temperature and a dual frequency acoustic sonar to characterize the bottom. The additional cost is small because we can use the same microcontroller and RF comm. link. A COTS, piezo `fish finder' transducer, drive and receive circuits will be added, along with signal processing software algorithms. Depending on deployment, this expendable, free floating sensor may wash ashore providing bottom information right up to the tidal zone. A small aperture and low transmitted acoustic power is sufficient for the shallow waters.(<60 feet) that are critical to special forces operations Benefits: industry or government entity might deploy these sensors to assist in recovery operations from an oil spill, hazardous waste response episode, or to monitor conditions during construction or other short-term operations not requiring a permanent measuring station Return
