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.
The wave velocity and radial velocity of radar wave Doppler positive and negative frequency shift signals are used to observe the wave propagation velocity of the intertidal shoal in the observation and test of high frequency ground wave radar in the shallow Beihai shoals in July 2011. Based on the frequency The data of wave velocity zonation of shoals in shoals of shoal shoal, underwater bank and tidal channel can be distinguished from the average wave velocity distribution of the shoals in northern Jiangsu after the data quality control of the shunting and the wave speed. The synchronization test shows that the radar Observed wave velocity and the observed depth of the relationship between the statistics Follow the theory of micro-amplitude wave, the radial velocity of the larger wave velocity observation under good conditions, complex terrain caused by two-way wave velocity inequality led to lower wave velocity observation quality, high frequency ground wave Radar is a potential tool for dynamic remote sensing monitoring of intertidal shoals.
