Abstract

Scintillation of pulsar radio emission provides information about the interstellar mediumalong the path to the pulsar and the velocities of pulsars. It also affects the precision of pulse timingobservations. Using a pulsar timing system developed at the Urumqi Astronomical Observatory 25 mtelescope, we observed diffractive scintillation dynamic spectra for several strong northern pulsars.This paper introduces the observing system and discusses the observational results.
