Abstract

Searching for a suitable very long baseline (VLBI) interferometer geometry is a key task in planning observations, especially imaging sessions. VLBI image quality is characterized by $(u, v)$ -coverage. With one or more radio telescopes located in space, such a task becomes more complex. This paper presents a method of recovering the optimal orbital parameters for space radio telescopes having a given desired $(u, v)$ -coverage. In turn, this task can be called the inverse of the task of searching for the optimal geometry and orbital configurations of space-ground and pure space VLBI interferometers.

根据空间无线电干涉仪的（u,v）覆盖率估算轨道参数

寻找合适的甚长基线（VLBI）干涉仪几何形状是规划观测，特别是成像会话的一项关键任务。甚长基线干涉仪的成像质量取决于（u,v）覆盖率。如果有一台或多台射电望远镜位于太空中，这项任务就会变得更加复杂。本文介绍了一种为具有给定所需（u,v）覆盖率的空间射电望远镜恢复最佳轨道参数的方法。反过来，这项任务也可以称为寻找空间-地面和纯空间 VLBI 干涉仪的最佳几何和轨道配置的逆任务。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
