Abstract
- OSMAR-S, a portable high-frequency surface wave radar (HFSWR), has been in operation for ten years in China for current mapping and shares more than 80% of the domestic HFSWR radar market. In this article, comprehensive quantitative validation and intercomparison of sea state parameter estimation from the OSMAR-S radar with multiple other sensors over a period of two months are presented. These sensors include five buoys temporarily deployed at range from 10 to 85 km away from the radar and another two types of commercially available phased-array (PA) radar made in China. A performance validation method of HFSWR compared with buoys deployed in both the high-precision area (HPA) and the edge area of the radar coverage is proposed for a full evaluation in a wide range area. A quantitative evaluation method using a variety of statistical metrics and their weights is proposed to obtain a comprehensive score for comparing the performance of different types of HFSWR. The good agreements with buoy data in a wide coverage area demonstrate the good capability of sea state parameters measurement using the OSMAR-S radar. Compared with the other two PA radars, OSMAR-S also shows a better performance in terms of accuracy and stability. [ABSTRACT FROM AUTHOR]
