高频地波雷达的东海试验

“高频地波雷达海洋环境监测技术”是由武汉大学主持的国家“863”计划海洋领域的重大课题，本课题组研制了两套高频地波雷达OSMAR2000，并于1999年底，在浙江省舟山市朱家尖和宁波市象山分别建立了两个雷达实验站，进行了一年的现场自检试验和与传统海洋测量仪器的对比验证试验.试验结果表明，雷达探测海流和海风的距离达到200km,探测浪高的距离达到120km，系统整体性能达到国外同类雷达20世纪90年代后期先进水平.

Test of HF Ground Wave Radar OSMAR2000 at the Eastern China Sea

The Radio Wave Propagation and Remote Sensing Laboratory of Wuhan University has successfully managed The HF Ground Wave Radar Technique in Monitoring Ocean Environment, one of the key marine projects in the national 863 plans of China. Two sets of HF ground wave radar systems named OSMAR2000 had been developed and deployed at Zhujiajian,Zhoushan city and Xiangshan,Ningbo city of Zhejiang Province, where the radar's selftest experiments and verification tests against insitu measurements by traditional marine instruments were carried out and lasted for one year. The results indicate that OSMAR2000's detecting coverage is 200km for currents and wind, and 120km for waves. OSMAR 2000 adopts FMICW wave form. Phased array is used both for transmitting and receiving.MUSIC and MVM algorithms are applied to achieve high resolution in current bearing determination.The integrated capacity of OSMAR2000 is believed to have reached the advanced level of the late 1990's.
