摘要
讨论了射电天线用于天文观测和VLBI大地测量时的几项性能参数;列出了我国现有射电天线组成系统时的工作性能和观测精度;计算了利用我国现有射电天线与FAST天线组成基线进行观测时的系统性能以及所要求射电源的最低流量密度。由此可以看出FAST天线用于VLBI观测具有巨大潜力。
Several capability indexes that have effect on the radio antenna are firstly discussed in this paper. The capabilities and precision of the existing radio antennas in VLBI observation are given, and then analyzing the system capability between FAST antenna and each of the existing radio antenna in VLBI observation.
