Abstract

Using the Kunming 40-m radio telescope at Yunnan Observatory, a Pulsar coherent de-dispersion experiment has been carried out, which uses a dual polarization receiver operating at s-band and a VLBA back-end: Mark5B+, whose highest sampling rate is 64MHz. The data processing system is based on the C programs on Linux. Some pulsar profiles had been carried out using the DBBC and Mark5B+ record system. In this paper we will discuss the application of the DBBC platform in pulsar observation domain and the algorithm of de-dispersion. The main purposes for the instrument are studies of pulsar mode changing, pulsar timing, scintillation monitoring, glitches, GPs (Giant Pulsars), etc.
