Abstract

A HF long-range (over 200 km) ocean radar system, developed by Japan´s National Institute of Information and Communications Technology, was used to observe the Kuroshio surface current in the southern part of the East China Sea. The observations began in July 2001. In this paper, we show the relationship between the antenna aperture length (beam-width) and the accuracy of Kuroshio surface current speeds measured using post-processed signals received by the radar
