Paper Abstract

Ultra-wide band (UWB) ground wave (GW) is a novel means of communications for use with distributed networked sensors at sea. Although multiple distributed sensor systems are in development, the communications method for these systems has yet to be fully realized. The buoys that relay the sensor information have several key features: they must be small enough so they are not highly noticeable and do not pose a navigation hazard; they must be cheap enough to be expendable; they must be able to run on limited battery power; the communications link must be at a great enough distance so that fewer buoys are needed; and they must deal with multipath from the sea surface. Ultra-wide band ground wave will address many of these issues. UWB is being developed commercially at 3-10 GHz. UWB requires low power and the transmitters are extremely easy to implement making the system inexpensive and small. UWB provides low probability of detection and interception. However commercial UWB operates at very short distances. Implementing UWB Ground Wave instead of commercial-band UWB will extend the communication range between buoys up to 10 miles. The distributed sensors will transmit to a central buoy for data relay via satellite or communicate directly to a submarine, UUV or surface ship antenna. This project is currently being funded by Office of Naval Research (ONR) 313. The project commenced in October 2005.
