Abstract

脉冲星脉冲到达时间观测系统建立在25m射电天线的18cm波段上,消色散采用了2×128×2.8MHz多通道滤波器和数字化器,数据采集系统由PC机完成,1999年5月至6月间建立了基于常温接收机的到达时间观测系统。观测到的最弱源的平均流量密度为4mJy。

Other Abstract

A pulsar timing observing system operating at 18 cm is developed for the 25 m radio telescope at Urumqi Astronomical Observatory. The de-dispersion is provided by a 2×128×2.5 MHz filter bank and digitizer, operated by a PC data acquisition system. The system is operational by mid-1999 with a room temperature receiver. The lowest pulsar flux density observable is 4mJy.
