  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
a 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, M3F, and detected the known pulsars M3B, M15 A to G
(except C), and M92A.
