Antenna Array plays very important roles in antijamming applications of GNSS receivers. A sound testing and experimental platform is needed to support the research of related algorithms, while an array signal simulator works as one of the key equipments. Based on the recent development of array signal simulators, this paper modeled array signals and focused on high precision control of array delays and calibration of array errors as the key problems. Various solutions of array signal delay simulation were analyzed. It will benefit the research and development of GNSS array signal simulators.
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.
