论文摘要
快速无线电爆发（FRB）的辐射反映了月球和太阳。如果检测到反射，则直接和反射信号之间的时间间隔将源限制在天空上的狭窄弧线上。如果检测到月球和太阳反射，这两个弧相交，狭窄地限制了天空上的源位置。先前的论文通过月球计算了反射。在这里，我们计算出“扁平太阳”近似值的太阳的反射率，这是入射角和频率角度的函数。反射率在频率$ \ Lessapprox 100 \，$ MHz和放牧发生率（Angles $ \ gtrapprox 60^\ Circ $）上很高，但对于频率$ \ Lessapprox 80 \，$ MHz的频率超过0.1。但是，太阳能电晕的强烈热发射可能排除了甚至像FRB 200428这样的MJY银河爆发的太阳反射的检测。
The radiation of a Fast Radio Burst (FRB) reflects from the Moon and Sun. If a reflection is detected, the time interval between the direct and reflected signals constrains the source to a narrow arc on the sky. If both Lunar and Solar reflections are detected these two arcs intersect, narrowly confining the source location on the sky. A previous paper calculated reflection by the Moon. Here we calculate the reflectivity of the Sun in the "flat Sun" approximation as a function of angle of incidence and frequency. The reflectivity is high at frequencies $\lessapprox 100\,$MHz and grazing incidence (angles $\gtrapprox 60^\circ$), but exceeds 0.1 for frequencies $\lessapprox 80\,$MHz at all angles. However, the intense thermal emission of the Solar corona likely precludes detection of the Solar reflection of even MJy Galactic bursts like FRB 200428.
