Abstract
Unlike traditional radiometers with quadratic amplitude detector these radiometers operate efficiently under the influence of narrowband radio interference. This paper presents the results of development of radiometers using the fast Fourier transform (FFT) digital signal sampling and selection of spectral components at frequencies of radio interference. There are two variants of the radiometric modules. The first model operating in the band video frequency (64 MHz). The second model can be connected to the output of intermediate frequency radio astronomy receivers 0.1-1 GHz

these radiometers operate efficiently under the influence of
narrowband radio interference. This paper presents the results of
development of radiometers using the fast Fourier transform (FFT)
digital signal sampling and selection of spectral components at
frequencies of radio interference. There are two variants of the
radiometric modules. The first model operating in the band video
frequency (64 MHz). The second model can be connected to the output
of intermediate frequency radio astronomy receivers 0.1-1 GHz
