Abstract

Experiments involving the radio sounding of solar plasma with signals from the Venus Express and Mars Express spacecraft, which were carried out from October 6 to December 6, 2006, provided data on frequency fluctuations of the radio signals for the western and eastern coronal limbs. The processing of this data provided information on the intensity of the frequency fluctuations, a parameter of plasma turbulence. High peaks of the intensity of frequency fluctuation were noted against the background of radial dependence; they can be explained by the passage of the compressed part of a corotating disturbance through a radio ray path. A delay in these events indicates a high-level connection of the fluctuations in the sounding radio-signal frequency within the same coronal region.

用金星快车和火星快车卫星探测超级日冕中的强湍流区域

摘要

2006 年 10 月 6 日至 12 月 6 日进行的涉及使用来自金星快车和火星快车航天器的信号对太阳等离子体进行无线电探测的实验，提供了关于西冕和东冕的无线电信号频率波动的数据。对这些数据的处理提供了关于频率波动强度的信息，这是等离子体湍流的一个参数。在径向相关的背景下注意到频率波动强度的高峰值；它们可以通过同向扰动的压缩部分通过无线电射线路径来解释。这些事件的延迟表明同一日冕区域内探测无线电信号频率的波动存在高度联系。
