Abstract
In order to study the detection performance of compact surface wave radar on ocean surface current in the west of Guangdong Province, firstly, the bistatic radar is set up to collect ocean echo data on the west coast of Guangdong Province. Then, by using the Multiple Signal Classification (MUSIC) algorithm, the comparative analysis results of ocean surface current information and the actual measurement results of DVS Current Meter are obtained. The root mean square error of flow velocity less than 10cm/s and the root mean square error of flow direction less than 25 degrees were obtained. It shows that compact surface wave radar can achieve good results and has good detection capability in the west of Guangdong, china.
Highlights
West Guangdong Sea, located in the southwest of the north of South China Sea, includes the sea from the west of Pearl River Estuary to the north of Hainan Island [1]
The coastal area of the west of Guangdong is a sea area closely related to the contemporary economic development, and its current state has an important influence on mariculture, material transportation and offshore engineering in this area
In order to effectively sup-port the development of Marine economy, it is necessary to carry out real-time, continuous and comprehensive monitoring of ocean surface current, and provide accurate multi-time and multi-scale Marine environmental forecast [2]
Summary
West Guangdong Sea, located in the southwest of the north of South China Sea, includes the sea from the west of Pearl River Estuary to the north of Hainan Island [1]. High frequency surface wave radar is the main tool capable of measuring ocean surface current state in a large range and with high precision, nearly 500 high frequency radar systems have been set up around the world[3]. These radar systems can be divided into two types in antenna form: array HF surface-wave radar based on beam-forming technology and compact HF surfacewave radar based on direction finding technology. It is relatively easy to locate, build and maintain the station, and has strong adaptability to installation It is the main direction of the development of high frequency surface wave radar. The performance of the Omar-S portable radar system is tested by the current measurement data of the current meter, and the trial situation of the Omar-S portable radar system in the sea area of the west of Guangdong is studied, so as to provide a useful reference for the application of the compact surface-wave radar in the sea area
