| Abstract: | A method of ionosphere absorption loss calculation is presented.By use of international reference ionosphere(IRI) model and the ray-tracing program on the discrete ionosphere background,the absorption loss of the High Freqnency Radar wave in the ionosphere is calculated quantitatively.The simulation results are given by the absorption loss under different wave frequency or different elevation angles.Some primary conclusions are given. |

| Keywords: | absorption loss High Frequency Radar frequency elevation angle |
