Clandestine ELOS/OTH RF Communications for Unmanned Underwater Vehicles

Abstract

The long term goal of this research is to identify fundamental issues and required technological developments for small long range communications systems utilizing HF ground wave propagation that can be used in extended-line-of-sight and over-the-horizon (ELOS/OTH) communications. Because ELOS/OTH transmission over water requires HF frequencies to diffract beyond line-of-sight, the sizes of standard antennas such as quarter wave monopoles are too large for UUV operation. Therefore, a major focus of this effort is on the development of electrically small antennas.
