摘要

摘要研究了日冕强规则折射(导致规则焦散和多径)对日冕湍流散射射电发射结构的影响。考虑了遥远的宇宙源和太阳自身的射电源。结果表明，对宇宙飞船无线电信号的能谱和太阳焦散阴影区脉冲星脉冲的平均剖面的观测可以用于日冕湍流诊断。强规则折射在太阳毫秒脉冲和带回波分量的太阳十米射电暴的形成中起着重要作用。

Coronal scattering of radio emission under strong regular refraction

Abstract The influence of strong regular refraction (that leads to regular caustics and multipathing) in the solar corona on the structure of radio emission scattered by coronal turbulence is investigated. Distant cosmic sources and Sun's own radio sources are considered. It is shown that observations of the energy spectrum of spacecraft radio signals and of the mean profile of a pulsar pulse in the Sun's caustic shadow zone can be used for coronal turbulence diagnostics. It is also shown that strong regular refraction plays an important role in formation of solar millisecond spike bursts and of type IIId solar decameter radio bursts with echo components.
