It has been about thirty years since HF surface wave radar was applied to ocean remote sensing.This paper introduces the experiment operated at the Eastern China Sea in Zhejiang Province Aug.2005 in the first
then presents the intercomparison results of HF surface wave radar system OSMAR2003 ocean current detection against in-situ measurements by ADCP.The results indicate the current detection accuracy of system OSMAR2003.The main error resources and characterizes of system OSMAR2003 are also drawn.
