Fast Radio Bursts (FRBs) are bright millisecond bursts whose origin are still in mysteries. Most of the world-wide radio telescopes have conducted FRB hunting project, and hundreds of FRBs have been published. In the early years, the single dish radio telescope takes the lead of FRB discoveries. Within High Time Resolution Universe (HTRU) by Parks, dozens of FRBs were found. The FRB110523, which are detected by GBT, bring the FRB filed into polarization observation. The recent break throughs of FRBs are more coming from the Telescope array. VLA announce the first Localization of FRB host Galaxy with its interferometer mode. Taking the advantage of large FoV by digital synthesized beams, CHIME declare its predominant space of FRB search. The early FRBs were detected from the archived Pulsar data, With the development of real-time search pipeline, the number of FRBs are increasing by leaps and bounds. In this talk, I would like to introduce how to build a FRB search pipeline based on my experience at FAST and TianLai telescope. Then some of the current de-dispersion algorithm will be discussed. In the end, I would share some new results of FAST-FRB discovery. |
