Ocean Surface Current Detection by HF Surface Wave Radar at the Eastern China Sea

Abstract

Abstract HF surface wave radar system OSMAR2000 adopts Frequency Modulated Interrupted Continuous Waveform (FMICW) and its antenna array is transmitting/receiving co‐used. MUSIC and MVM are applied to obtain sea echo's direction of arrival (DOA) when extracting current information. Verification tests of OSMAR2000 ocean surface dynamics detection against in‐situ measurements had been accomplished on Oct. 23~29, 2000. This paper introduces the radar system and the applied DOA estimation methods in the first, and then presents comparison results of surface current measurements in the verification tests. The results indicate the validity of the developed radar system and the effectiveness of the applied signal processing methods.
