Collision avoidance radar for trains is significant for safe transportation. In order to realize a low cost collision avoidance radar and high performance of azimuth accuracy, we have developed MMW (millimetre wave) radar, which employs switched phased array and frequency stepped technology. This paper analyses the radiation patterns of transmitting/receiving antennas and compensation method for amplitude/phase errors of synthetic wideband frequency stepped radar. To confirm the operation of the radar, low cost millimetre-wave collision avoidance radar was fabricated.Lots of experiments confirmed a high azimuth and range resolution.
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.
