IONOSPHERIC SCINTILATION OF COSMIC RADIO NOISE
-
摘要: 本文给出了薄相屏近似条件下的电离层闪烁Fourier功率谱和Bessel功率谱与电离层不均匀结构电子密度涨落空间谱之间的关系。对窄波瓣天线Riometer获得的宇宙噪声资料进行了分析,结果表明:宇宙噪声资料包含着电离层不均匀结构的信息。Riometer观测结果也可用于电离层闪烁问题的研究。Abstract: This paper gives the relation between the Fourier and Bessel power spectra of ionospheric scintilation and the fluctuations in electron density of irregularities when a thin phase-screen approximation is justifies.And analysed the data obtained by Riometer with narrow lobe-beam antannas.It shows that the Riometer data contain the information of irregularities in the ionosphere,and these data could be used to study the ionospheric scintilation.
