摘要
基于数字射线追踪技术,以球形对称准抛物电子浓度模型作为背景的电离层模型,建立了返回散射电离图仿真平台,并利用该平台对电离层存在梯度、Es、扰动等典型电离层状态的返回散射电离图进行了仿真,最后讨论了天线方向图对返回散射电离图的影响。
Based on the digital ray Iracing technique, a simulation platform of back scatter ionogram is built by using symmetrical quasi-parabolic model as background ionosphere. And the typical backscatter ionograms such as ionosphere with gradient, Esand disturbance are simulated. In the end, the influence of antenna pattern on the backscatter ionograms is discussed.
