摘　　要：提出了一种计算电离层吸收损耗的方法。利用国际参考电离层模型(IRI)和离散电离层背景下的射线追踪模型,对穿过电离层区域的高频雷达电波的吸收损耗进行了定量分析,得到了在不同电波频率和不同发射仰角情况下的吸收损耗的模拟结果,并给出了初步结论。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.

关 键 词：吸收损耗 高频雷达 频率 仰角
