Medium wave multi-section groundwave propagation in Marmara and West Black-Sea region-numerical results
Abstract
The medium wave (MF) propagation in maritime communication system in the Black Sea region was numerically analyzed. Two methods were applied: the flat ground two and four section ground wave propagation, and the integral equation solution. Attenuations up to 400 km are needed for estimating the requirements on the transmitter power and the effective antenna height for manageable signal to noise ratios at this particular frequency. The four section formula obtained represents an efficient technique for prediction attenuation for the last sea section of the propagation path. It is shown that MF ground wave is a suitable mode of propagation for ship to shore communication system.
