Research And Implementation Of Pulsar Single Pulse And Scintillation Domain Data Processing Platform

Five-hundred-meter Aperture Spherical Telescope(FAST) is built according to the Karst topography, with independent intellectual property rights, one of the “11th five-year” science and technology major infrastructure projects in China. It will be the largest aperture radio telescope with highest sensitivity. One of the goals of FAST early science is to carry out the research in the field of pulsars.In radio pulsar astronomy, individual pulse and scintillation are two basic research field, there have three important observations, pulse “nulling” and sub-pulses “drifting” and scintillation phenomenon. Studies the three observations can help pulsar workers understand pulsar emission mechanism and the attributes of interstellar medium. Studies in these domains are key projects planned for FAST.As part of the construction of FAST pulsar data-analyzing software platform, in the present work, the shared libraries of PSRCHIVE, an internationally wide-used software package for operating fold-mode data that are in PSRFITS format, are used for the design of the programs, PEM(Pulse Energy Measurer), PDA(Pulse Drifting Analyzer) and PSA(Pulsar Scintillation Analyzer). These programs are used for the data analysis for the studies on individual pulses' energy distribution, sub-pulse drifting and strong diffractive scintillation respectively, which will be used for carrying out relevant studies with FAST.
