A multistatic high-frequency (HF) ocean radar is proposed that could be used both for surface current mapping and ship tracking. Through fine tuning the carrier frequency of the transmitting signals, echoes produced by different transmitters could be separated in the baseband. Shore-based Automatic Identification Systems (AIS) are used for receiving antenna calibration and ship tracking result verification. A two-month experiment was conducted on the coast of the North China Sea from October to December in 2013. The primary data processing results prove the effectiveness of the radar system.
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.
