摘要 We present a pulsar candidate identification and confirmation procedure based on a position-switch mode during the pulsar search observations.This method enables the simultaneous search and confirmation of a pulsar in a single observation,by utilizing the different spatial features of a pulsar signal and radio frequency interference(RFI).Based on this method,we performed test pulsar search observations in globular clusters M3,M15 and M92.We discovered and confirmed a new pulsar,M3 F,and detected the known pulsars M3 B,M15 A to G(except C) and M92 A.
