随着一个新的相控阵系统的安装，韦斯特博克综合射电望远镜（WSRT）的瞬时视场增加到8.7 deg 2。该系统使WSRT成为一个高效的望远镜，可以进行快速射电爆发（FRB）和脉冲星调查。为了利用这一优势，WSRT正在开发和调试一个先进的实时后端，称为“无线电瞬变系统”（ARTS）。除了实时检测FRB外，ARTS还将事件定位到约1/2600的视场-这是识别FRB性质的基本信息。ARTS还将触发新检测到的FRB的LOFAR实时跟踪，以实现角秒精度的定位。我们回顾了即将到来的时域调查，并提出了目前的状态正在进行的调试的时域功能的foctif。
With the installation of a new phased array system called Apertif, the instantaneous field of view of the Westerbork Synthesis Radio Telescope (WSRT) has increased to 8.7 deg2. This system has turned the WSRT in to an highly effective telescope to conduct Fast Radio Burst (FRB) and pulsar surveys. To exploit this advantage, an advanced and real-time backend, called the Apertif Radio Transient System (ARTS), is being developed and commissioned at the WSRT. In addition to the real-time detection of FRBs, ARTS will localize the events to about 1/2600 of the field of view — essential information for identifying the nature of FRBs. ARTS will also trigger real-time follow up with LOFAR of newly detected FRBs, to achieve localization at arcsecond precision. We review the upcoming time-domain surveys with Apertif, and present the current status of the ongoing commissioning of the time domain capabilities of Apertif.
