Article

We consider the operation principle of a spectral-selective radiometer unit with a bandwidth of up to 1 GHz, which calculates the spectra of the signals received by the antenna in real time with the subsequent exclusion of spectral components at the radio-interference frequencies. The latter allows one to perform radiometric measurements in continuum when exposed to radio-frequency interference without using the filtering methods of its selection in the widedband radiometer receiving channel. Under the radio-interference action, the observation results confirm the high accuracy of the radiometric measurements in continuum, which were conducted using the radio telescopes of the “Kvazar-KVO” complex.
