Abstract:We address the problem of co‐channel interference (CCI) in multi‐channel airborne passive radars using digital broadcast signals of opportunity. A framework for suppressing the CCI is proposed, based on a two‐stage approach, which reflects the range–Doppler map being a function of both a reference and a surveillance signal. In the first stage, the multiple receiving channels are used to reduce the CCI and hence improve the reconstruction of the digital reference signal. In the second stage, multi‐channel proce… 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.
