摘　　要：通过对电离层探测数据的处理,得到电离层的水平不均匀性模型。对这种水平不均匀电离层模型进行射线追踪,应用变步长射线追踪方法对赤道双峰模型进行射线追踪。电离层射线追踪的路径反映了电子密度和折射率的水平不均匀性,对电离层的斜向探测具有重要的价值。By processing the data of ionosphere detection we obtain the model of ionosphere, which is asymmet- ric in the horizontal direction. The method of ray tracing is used in the model of asymmetric ionosphere. The stepchanging technology is used in the ray tracing of the equator two-humped model. The asymmetry of electron concen- tration and index of refraction in the direction of horizontal is well reflected by the path of the ray tracing, which is valuable in ionosphere oblique sounding.
