Shortwave Propagation over Oceans and HF Propagation Prediction Model

The characteristics of rough seas´ propagation in HF band are analyzed in this paper. Sketch of the transmission model and characteristics of HF band are firstly introduced. The ground-wave propagation is particularly investigated and the sky-wave propagation model is introduced marginally. After the sky-wave transmission path was detailed and analyzed. The simulation results of ICEPAC (Ionospheric Communication Enhanced Profile Analysis and Circuit Prediction Program) show that HF prediction model built with correct settings outputs the general communication situations of China rough sea in HF band and improve the receiving communication reliabilities.
