摘要

摘要本文研究了在甚长基线（VLBI）空间射电干涉仪上使用多频合成方法的可能性，以改进（(u,{v})\）覆盖范围和由此产生的合成图像的质量。为了评估多频合成方法的贡献，以基于圆形近地轨道组合的空间 VLBI 概念为例，对 VLBI 观测进行了模拟。

Multi-frequency Synthesis in Space Very Long Baseline Radio Interferometry

The paper examines the possibilities of using multi-frequency synthesis methods for very long baseline (VLBI) space radio interferometers to improve the \((u,{v})\) coverage and the quality of the resulting synthesized images. To evaluate the contribution of multi-frequency synthesis methods, simulations of VLBI observations were performed using the example of the space VLBI concept that is based on a combination of circular near-Earth orbits.
