摘要

中国科学院空间科学战略重点研究项目“空间毫米波VLBI阵列(SMVA)”,旨在建设世界上第一个空间毫米波甚长基线干涉测量(VLBI)阵列。SMVA具有地面VLBI阵列无法达到的最高20微弧秒的超高空间分辨率,是对黑洞和其他致密天体周围超精细发射结构进行成像的有力工具。紫外覆盖仿真、数值仿真和图像仿真在项目的各个阶段都起着至关重要的作用,因此设计并实现了空间VLBI仿真软件。该软件具有所有必要的和辅助的仿真功能。与其他同类软件包相比,它具有许多优点:它的界面更友好,软件包健壮且独立于操作系统,代码更容易扩展和扩展。

Space millimeter-wavelength very long baseline interferometry simulation software
The Strategic Priority Research Program on Space Science of the Chinese Academy of Sciences, “Space Millimeter-wavelength VLBI Array (SMVA)”, aims to build the first space millimeter-wavelength Very Long Baseline Interferometry (VLBI) array in the world. The SMVA, which has the ultra-high spatial resolution with a best of 20 micro-arcsecond that a ground-based VLBI array can not attain, is a powerful tool in imaging the hyperfine emission structure surrounding the black holes and other compact celestial objects. The simulations, such as UV coverage simulation, numerical simulation and image simulation, play a crucial role in all phases of the project, so a space VLBI simulation software was designed and implemented. This software has all the necessary and auxiliary simulation functions. And it has many advantages compared to other similar software packages: its interface is more friendly, the software package is robust and independent of operation system, the code is much easier to expand and scalable.
