摘要

摘要本文研究了利用多频合成法提高千米强子观测站的空地甚长基线射电干涉仪模式所获图像质量的可能性。对超大质量黑洞 M87 附近的成像观测进行了模拟。显示了多频合成与单频观测相比的优势。提出了将多频合成应用于千米子观测站的空地干涉测量的要求和限制。

Evaluation of Millimetron Observatory Capabilities in Interferometer Mode Using Multifrequency Synthesis

The paper examines the possibilities of using the multifrequency synthesis method to improve the quality of images obtained by the space-ground very long baseline radio interferometer mode of the Millimetron observatory. Simulation of imaging observations for the close vicinity of the supermassive black hole M87 was carried out. The advantages of multifrequency synthesis compared to single-frequency observations are shown. The requirements and limitations of its applicability to space-ground interferometry with the Millimetron observatory are formulated.
