Abstract:A phaseless setup for a submillimetre‐wave frequency scanning‐based radar system is presented. The phase retrieval setup is implemented by modifying a previous implementation at microwave frequencies. In the new setup, the number of involved components (e.g. directional couplers, power combiners etc.) is reduced by including a time‐domain reference signal by means of direct radiation, yielding a low‐cost submillimetre‐wave radar system that avoids the need for phase shifters. Several measurement examples are s… 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.
