Stability and increased radio communication coverage of sea area infrastructure measurement antennas

Abstract

This research presents a modified method of signal amplification over layered surfaces of absolutely thin ice over marine waters on condition of stable operation of communication networks, necessary for deployment of Big Information Management Communication Systems and the concept of E-Navigation development. The method was first tested when deploying a GMSSB(b) network in the Azov-Black Sea region. Peculiarity of radio wave behavior during propagation over thin layered ice is that mutual phase ratios make a part of field energy “sticking” to the surface and propagating along it, thus creating a surface wave effect. At that, attenuation function is above one, and the field may increase with distance, even above design limits, breaking the proportionality law of reduction with distance. There are several details requiring clarification and adjustments to local conditions.In the MF and LF radio bands, solid surface and sea water are good conductors of electromagnetic flow. Thus, antenna fields for radio communications are located immediately above the surface for reception and transmission of vertical polarization signals, while field calculations are conducted with an elementary dipole.
