平方公里阵列将是脉冲星天文学的一个惊人的仪器。虽然完整的SKA将足够敏感,可以检测到从地球上可见的银河系中的所有恒星,但已经有SKA1,脉冲星搜索将发现足够的恒星,使目前已知的恒星数量增加四倍,毫无疑问,包括一系列令人惊叹的未知来源。需要真实的时间处理来处理每天收集的60 PB的脉冲星搜索数据,使用执行超过10次POPS所需的信号处理流水线。在这里,我们提出了SKA脉冲星搜索引擎的设计建议,并讨论了脉冲星搜索企业的挑战和解决方案。
The Square Kilometre Array will be an amazing instrument for pulsar astronomy. While the full SKA will be sensitive enough to detect all pulsars in the Galaxy visible from Earth, already with SKA1, pulsar searches will discover enough pulsars to increase the currently known population by a factor of four, no doubt including a range of amazing unknown sources. Real time processing is needed to deal with the 60 PB of pulsar search data collected per day, using a signal processing pipeline required to perform more than 10 POps. Here we present the suggested design of the pulsar search engine for the SKA and discuss challenges and solutions to the pulsar search venture.
