论文摘要
我们提出Omniuv,这是一种用于空间和地面VLBI观测值的多用途模拟工具包。它支持各种vlbi站,包括固定地球(地面),地球轨道,固定的月球,月球轨道,月球 - 地球和sun-sun-sun-sun lagrange 1和2点等。该工具包的主要功能是:(1)轨迹计算; (2)基线紫外线计算,通过考虑每个电台的可效性; (3)给定的UV分布,源结构和系统噪声的可见性模拟; (4)图像和光束重建。两种情况,即空间VLBI网络和广阔场数阵列,以完全不同的尺度的工具包应用程序的演示。 Omniuv是“无所不能紫外线”的首字母缩写。我们希望它可以作为一个通用框架,在其中可以轻松地合并各种站点,并且可以进一步扩展功能。该工具包已公开可用。
We present OmniUV, a multi-purpose simulation toolkit for space and ground VLBI observations. It supports various kinds of VLBI stations, including Earth (ground) fixed, Earth orbit, Lunar fixed, Lunar orbit, Moon-Earth and Earth-Sun Lagrange 1 and 2 points, etc. The main functionalities of this toolkit are: (1) Trajectory calculation; (2) Baseline uv calculation, by taking the vailability of each station into account; (3) Visibility simulation for the given uv distribution, source structure and system noise; (4) Image and beam reconstruction. Two scenarios, namely space VLBI network and wide field array, are presented as demonstrations of the toolkit applications in completely different scales. OmniUV is the acronym of "Omnipotent UV". We hope it could work as a general framework, in which various kinds of stations could be easily incorporated and the functionalities could be further extended. The toolkit has been made publicly available.
