基于超高频雷达的湖面风浪参数提取

Extraction of Wave Height Parameters and Wind Field from Ultra High Frequency Radar Sea Echo Doppler Spectra

基于Barrick的微绕散射理论,在超高频雷达USCR工作频率条件下,将反演均方高浪高公式应用于超高频雷达USCR提取湖面风浪信息,在国内首次实现从湖面回波多普勒谱中获取了浪高信息;并利用Heron理论,由浪高信息反演出风速风向信息;通过模拟相同风浪状态下的湖面回波,并进行对比证明本方法是行之有效的。

Based on Barrick＇s equation of perturbation method,under the UHF radar USCR band condition,this paper applys the high-mean-square wave height formula to extract information about the lake wave.From the Ultra-high frequency radar＇s sea echo,the paper for the first time obtains the wave height from the lake echo,and utilizes the Heron＇s theory to induce the wave speed and direction information from the doppler spectra.The effective of the method is verified by the comparison between measurement and simulation results.
