Long-Range High-Bandwidth At-Sea Datalinks
Abstract
The project is focused on the test campaign performed with electromagnetic signals propagating above sea in warm climate. The interest is in broadband radio signals propagating at short and very long distances such as beyond the optical and the radio horizon defined with classical scientific formulations. Effects of the Earth curvature are investigated experimentally during day and night experiments. Antennas at opposite ends of the test radio link are to bemounted on the shore station and on mobile stations, including a vessel considerably obscured by the curvature of the Earth. Furthermore, sea state influence on fading and other aspects of electromagnetic wave propagation are investigated. The complete set of parameters describing electromagnetic waves such as center frequency and bandwidth, wave polarization (single and dual-polarized), antenna heights, waveform and its modulation, energy spectral density will be investigated during experiments. The test program is based on the legacy of other projects executed by Wroclaw University of Science and Technology (WUST) and by Naval Postgraduate School in Monterrey as well as other electromagnetic over sea scientific programs. The most recent tests were run in December 2019 and January 2020 at Zatoka Gdanska in Poland. The results of these tests have confirmed results from 2015 and 2016 as well as validity of theoretical analysis carried out. Last but not least, the most recent tests were extended onto new waveforms.
