Abstract

This paper considers the possibility of the deep trough formation in the integral amplitude–frequency dependence of the wave field at the classical limiting paths of a single-hop ionospheric radio waves propagation under conditions of low solar activity. Calculations based on the global ionospheric model with both standard (IRI) and alternative dynamic (IRI + GDMF2) representations of the F2 layer of the ionosphere are compared with the experimental results of multifrequency oblique ionospheric sounding (OIS). It is shown that it is fundamentally possible to use the model to describe this feature based on the energy parameters of the radiation transfer problem in the ionosphere.

在低太阳活动条件下限制单跳无线电路径的波场功率参数的频率依赖性

摘要

本文考虑了在太阳活动低的条件下，单跳电离层无线电波经典传播路径在波场的积分振幅-频率依赖性中形成深谷的可能性。基于与两个标准（IRI）和替代动态（IRI + GDM全球电离层模型计算˚F 2）的表示˚F 2层的电离层的与多频斜电离层探测（OIS）的实验结果进行比较。结果表明，从根本上可以使用该模型基于电离层辐射传输问题的能量参数来描述此特征。
