摘　　要：甚长基线干涉测量(VLBI)是至今唯一能够同时提供天球参考架(CRF)、地球参考架(TRF)以及地球定向参数(EOP)的空间测地技术。本文介绍了佘山13米射电望远镜(Sheshanl3)的设计和实现,以及系统的关键组成部分,包括天线、低温接收机、上下变频(UDC)、数据采集、时频和监控软件等;并给出了一些典型的系统性能测试和条纹检测初步结果,即某些技术问题需要之后进一步讨论和研究,整个系统还需要更多的测试和改进。Currently very long baseline interferometry(VLBI)is the only space geodetic technique that can provide the celestial reference frame(CRF),the terrestrial reference frame(TRF),and the Earth orientation parameter(EOP)simultaneously.The design and implementation of the Sheshan 13-m radio telescope is described in this paper,and the key components of the system are also introduced,including the antenna,cryogenic receiver,up-down converter,data acquisition,time frequency and monitor and control software.Some preliminary results of typical systematic performance and stripe detection are presented.However,some technique issues require further discussion and investigation,and the whole system asks for more testing and improvement.
