Elektronik Harp Geniş Bant Almaçlarda Enterferans Etki Analizi

Abstract

Isik UniversityIn electronic warfare systems, wideband receivers are used to continuously monitor threat signals in the electromagnetic environment. In a modern threat environment, radar signals coexist with various communication signals within the same frequency band. These signals create interference in wideband receivers, hindering the accurate measurement of radar signal parameters. Interfering signals cause varying levels of distortion in digital and analog wideband receivers. In this study, the wideband FFT and instantaneous frequency measurement algorithms are utilized to analyze the impact of parameter estimation under different Signal-to-Interference Ratios (SIR), and their performance is analyzed with different FFT sizes under QPSK modulation. © 2025 Elsevier B.V., All rights reserved
