The backend system with a spectral rejection of radio-frequency noise for broadband radiometer

S. Grenkov, N. Koltsov

Transactions of IAA RAS, issue 21, 304–311 (2010)

Keywords: радиоинтерферометрия со сверхдлинными базами, широкополосный радиометр, спектральная селекция радиопомех

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
