赤道电离层F区底部准正弦型不均匀体引起闪烁的数值模拟

NUMERICAL SIMULATION OF SCINTILLATION ASSOCIATED WITH BOTTOMSIDE SINUSOIDAL IRREGULARITIES IN THE EQUATORIAL F REGION

本文采用多重相屏模型,考虑不均匀体特征尺度随高度的变化,模拟了赤道电离层F区底部准正弦型(BSS)不均匀体引起的闪烁 。模拟计算结果表明:BSS不均匀体的特征尺度随高度变化可以导致闪烁谱和不均匀体谱之间谱指数的显著差异。

In this paper a multiple phase-screen model is used to simulate the scintillation arising from bottomside sinusoidal (BBS) irregularities in the equatorial F region. The simulation shows that the variation of irregularity characteristic scale with altitude can result in large difference in spectral index of scintillation power spectrum and irregularity power spectrum.
