HF Backscatter Ionograms on Propagating Across the Equatorial Anomaly

本文主要展示黑子高年冬季跨赤道异常区传播试验的高频返回散射电离图。指出了有一类双回波区混合型P′(f)电离图是属新的形态。讨论了电离图的日变化与探测路径电子浓度双驼峰分布的日变化的一致性,指出利用高频返回散射技术研究赤道异常区北峰漂移规律,研究南中国海高频雷达和高频通信实时选频方法的可用性。

In this paper the experimental HF backscatter ionograms on propagating across the equator -ial anomaly during the winter in high sunport years are presented. It is showed that the double echo region ionograms with mixed PP(f)mode belongs to the new kind of the backscatter ionograms. The identity of the daily variable between the ionograms and the electron density distribu -ation of equatorial anomaly is discussed. The availability that the backscatter sounding technique study the law on the moving of the northern crests of the equatorial anomaly and The frequency management on HF OTH-B radar and communication in the south China Sea region are found.
