论文摘要
我们提出了使用一组假设的封闭阵列望远镜进行的调查的预计快速无线电爆发检测率。此类调查的成本效率至少与调查频率的反平方相反。在0至25 $ \ rm {m^2} $范围内有一个最佳数组元件有效区域。如果FRB集成源计数与通量的功率定律指数$α= d〜ln r/d〜ln f> -1 $最具成本效益的望远镜布局使用单个偶极子元素，则提供了全天空的视野。如果$α<-1 $ $盘阵列更具成本效益。
We present projected Fast Radio Burst detection rates from surveys carried out using a set of hypothetical close-packed array telescopes. The cost efficiency of such a survey falls at least as fast as the inverse square of the survey frequency. There is an optimum array element effective area in the range 0 to 25 $\rm{m^2}$. If the power law index of the FRB integrated source count versus fluence $α= d ~ln R/d ~ln F > -1$ the most cost effective telescope layout uses individual dipole elements, which provides an all-sky field of view. If $α<-1$ dish arrays are more cost effective.
