时延-角度特性研究

ANALYSIS ON THE PROPERTIES OF THE RELATIONSHIP BETWEEN TIME-DELAY AND TAKE-OFF ANGLE

本文在球不对称局域准抛物电离层模型下,设计了一套射线追踪算法的计算机程序。研究了时延随角度变化特性。指出了最小时延的传统求解方法的适应范围,讨论了时延-角度特性曲线与返回散射电离图的关系及其能量分布特点。

In this paper, the computer algorithm of the ray tracing in a sphyerically asymmetric and locally quasi parabolic electron density model is presented. The property curve of the variation of the group time-delay with the take-off angle is analyzed. The limitations of the traditional algorithm used in obtaining the minimum group time-delay is pointed out, and discussed of the correlation of the property curve with the backscatter ionogram are made. Properties of the power distribution on the backscatter ionogram is also discussed.
