摘　　要：天马望远镜是目前亚洲最大的全方位可转动的射电望远镜。连续谱观测对于天马望远镜具有重要意义。主要介绍天马望远镜连续谱观测系统的相关信息及其实现情况,包括:天马望远镜连续谱观测的过程、天马望远镜连续谱观测系统的硬件和软件系统的组成,以及连续谱观测系统的测试观测结果。在C波段6.5 GHz的观测结果表明:连续谱观测系统可实现单点观测和成图观测。修正后指向误差的平均值为2.2″,均方根误差为4.3″。目前该系统已用于天马望远镜的连续谱观测,取得了较好的结果,验证了系统的有效性。The Tianma Radio Telescope(TMRT)is the largest and fully steerable radio telescope in Asia.The continuum observation is important for the TMRT.In this paper,we provide the information and implementation of the continuum observing system in the TMRT.The speci c contents are as follows:section 2 demonstrates the continuum observing process,section 3 presents the hardware and software systems of the TMRT continuum observing system,section 4 shows the test observation results in C band at 6.5 GHz.The system can be used for single-point and map observation.The mean and root mean square of the pointing error is 2.2″and 4.3″after correction.At present,the continuum observing system has been used as a regular observation mode of TMRT,and has obtained good results which veri es the reliability of the system.
