Research on Suppresion System Analysis of High Power Narrowband Interference Operating in Presence of Heterodyne Frequency

Abstract

The study is considered with the process of suppressing the narrowband interference which acts close to heterodyne frequency. the purpose of the study is to analyze the scheme in the structure of the radiometric receiver for narrowband interference suppression in presence of heterodyne frequency with the help of analytical analysis method. This method is based on automatic interference detection, its overlapping with heterodyne frequency and supporting heterodyne signal. the principle of modulation radiometer is realized in the interference suppression scheme. the modulation radiometer contains voltage switching center of “meander” type which controls highly-quality driving tool, total stress and phase detector. Circuits of automatic tuning frequency and heterodyne amplitude control are independent and operate permanently.
