Abstract

At present, radio interferometry with a very long baseline (VLBI) is the most advanced measuring method, which allows us to obtain high-quality images of astronomical objects with the highest angular resolution. Multi-frequency synthesis (MFS) in VLBI involves mapping a radio source sequentially at several frequencies in order to improve the filling of the UV-plane and, thereby, to improve the quality of the synthesized images. This article presents the results of observations of the radio source W49N using a radio engineering complex installed on antennae in Pushchino and Simeiz. The software for automatic control of the receiver frequency tuning and calibration measurements was also developed.

AB  - At present, radio interferometry with a very long baseline (VLBI) is
the most advanced measuring method, which allows us to obtain high-
quality images of astronomical objects with the highest angular
resolution.  Multi-frequency synthesis (MFS) in VLBI involves mapping
a radio source sequentially at several frequencies in order to
improve the filling of the UV-plane and, thereby, to improve the
quality of the synthesized images.  This article presents the results
of observations of the radio source W49N using a radio engineering
complex installed on antennae in Pushchino and Simeiz. The software
for automatic control of the receiver frequency tuning and
calibration measurements was also developed.
