英文摘要	应用雷达波dOPPlEr正频移与负频移信号联解波速和径向流速方法,在2011年7月苏北浅滩高频地波雷达观测试验中实现潮间浅滩海面波浪传播速度的观测.基于频移与波速两级数据质量控制后统计的苏北浅滩平均波速平面分布图,可分辨出与潮间浅滩、水下岸坡和潮汐水道等浅滩地貌单元相关的波速分区格局.同步检验表明:雷达观测波速与现场观测水深的关系统计意义上遵循微幅波理论,径向流速较大条件下的波速观测质量较好,复杂地形所致双向波速不等现象导致波速观测质量降低,高频地波雷达是潮间浅滩动态遥感监测的潜在工具.; High-frequency(HF) radar systems can provide wave velocity and radial current by identifying and tracking frequency shifts in the peaks of the Doppler spectra of the ocean backscatter corresponding to the advection of the Bragg wave.Data used in this study was collected by HF radar experiment for the Northern Jiangsu Shoal in July 2011.A distribution of monthly average wave velocity was generated with data that is quality controlled particularly.The intertidal flat, offshore shoal and tidal channel, associated with low speed area, high speed area and high speed belt respectively, could be distinguished by the HF radar mapped wave velocity distribution.After compared with datasets of field measurement and calculate results, it is revealed that(1) the relationship between water depth and monthly average wave velocity fits the theory of Airy Wave,(2) large radial currents may rise measurement accuracy of wave velocity, and 3) mismatch of approaching and leaving wave velocity related to complex topography may reduce measurement accuracy.; 海洋公益性行业科研专项经费(201005012;201005006); 国家自然科学基金(40876031); 国家高技术研究发展计划(2012AA091701); 江苏省科技计划项目基础研究计划(SBK201150144)资助
