| 摘 要： | 本文给出了太阳黑子高年冬季跨电离层赤道异常区传播试验的高频返回散射电离图.经过分类研究,指出了有一类双回波区组合型P ′（f）返回散射电离图是一种新的形态.通过射线追踪合成技术分析,表明了这类型实验返回散射电离图是沿探测路径存在双峰电子浓度分布的反映,时序电离图的变化特征显示了赤道异常区的电子浓度变化规律,因而证明了高频返回散射技术在研究赤道异常区电离层峰运动的可能性及其潜力.

| Abstract: | In this paper, the experimental backscatter ionogrames which obtained by the experiment have done to observed southward the equatorial abnormal in Xinxiang during the winter of high sunpot period, are presented and classified. It is pointed out that the double regions iono-grame with mixed P'(f) mode appears newly and is responsible of the double peaks distribu-tion of electron density in ionosphere along the observed path, and the time history ionogrames marked the variable law of the electron density in equatorial abnormaly area. It is indicated that HF backscatter technique to research equatorial abnormaly is not only a feaisble method, but a good potential. |
