【摘要】 一般认为高频无线电波经电离层反射后产生的多普勒频移效应可分为两部分:其中一部分只与反射面的状态有关,这部分称为微分效应;另外一部分与电波所经过的路径上介质的状态有关,这部分称为积分效应。本文分析高频无线电波在电离层中的反射过程,认为不存在微分效应,只存在积分效应,并用这结论分析了实验现象,讨论了用多普勒测量法研究电离层行进式扰动时存在的问题。更多还原

【Abstract】 According to the general consideration, the effect of ionosphere on the frequency variation of the reflected HF radio waves consists of two parts, the differential effect, which depends only upon the state of the medium at the point of reflection, and the integral effect, which depends upon the states of the media along the whole ray path. In the present paper, a study of the mechanism responsible for both effects is made. The conclusion is that only the intergral effect exists while the differential effect does not. According to this conclusion, some experimental results may be ex-plained. Problems related to the TID’s research by means of Doppler measurement have also been discussed.更多还原
