Abstract:A novel radar adaptive jamming suppression method based on joint time-frequency transformation is proposed. Confronting the challenges of non-stationary jamming signals that radar receives, a new technique is presented to deal with them. Firstly, the time-frequency characteristics of radar received signal are analyzed by short-time Fourier transform (STFT). Secondly, an adaptive filter function is constructed in STFT domain. By applying a proper threshold to the timefrequency modulus spectrum (TFMS), strong ja… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
