As an important instrument for sea states monitoring, the portable high frequency surface wave radar (HFSWR) OSMAR-S was installed at the Honghai Bay of Shanwei, Guangdong Province to provide sea weather forecast services for the 16th Asian Games Sailing Competition in November, 2010. The radar achieved continuous echo data and sea state parameters of the sea area for nearly 1 month, including current velocity, current direction, wave height, wave period, wind speed and wind direction. The radar-measured sea states are compared with the in-situ measurements by multiple instruments such as ship-borne current meter, anemometer and in-situ deployed buoys. The comparison results show good coincidence between measurements by radar and in-situ instruments, which preliminarily validates the capability of radar on monitoring coastal sea states, especially wind and wave. ©2012 by Editorial Department of Chinese Journal of Radio Science.

A multistatic high-frequency (HF) ocean radar is proposed that could be used both for surface current mapping and ship tracking. Through fine tuning the carrier frequency of the transmitting signals, echoes produced by different transmitters could be separated in the baseband. Shore-based Automatic Identification Systems (AIS) are used for receiving antenna calibration and ship tracking result verification. A two-month experiment was conducted on the coast of the North China Sea from October to December in 2013. The primary data processing results prove the effectiveness of the radar system. © IEICE 2014.

In order to test the measurement capability of HF ground wave radar system (OSMAR-S) with compact receiving antenna, verification tests of OSMAR-S system againstin situ measurements had been accomplished on Nov. 12~17, 2007. A observation method is used in the test for continuously comparison. The method is composed of fixed point survey at fixed depth and section survey at bottom, and compared the surface current data acquired by OSMAR-S with different depth current data acquired by others. The results confirm the detection precision and depth of OSMAR-S and indicate OSMAR-S is meet the need of sea real-time monitoring. The test also fill the blank that it is no test to confirm the detection depth of HF ground wave radar.
