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。
