- The HF radio waves can travel long distances using the multi-hop paths between ionosphere and the earth. When the radio waves reflect from the surface of ocean, they are sometimes affected greatly due to the turbulent ocean surface. In this article, we study the impact of the turbulent ocean on multi-hop radio propagation, analyzing different effects of every parameter on the reflection of radio waves from the surface of ocean. We analyze the reflection process from the ionosphere and the effective factors to the ionospheric transmission loss. We find that in the high frequency band, the value of Li stays at a relatively low level. Then, the calculation formulas about the reflection coefficient are shown, which are obtained in the bibliographies. We use MATLAB to simulate the fluctuation of the turbulent ocean surface according to the two-dimensional wave equation. Then we add the light equation into the model, and calculate the reflected direction. With a pre-set screening conditions, we get the proportion of beams that can keep travel forward. As a simplified model, we regard the ratio of these beams as the reflection coefficient. The coefficients in different situations of turbulent are shown respectively.
