摘要
根据海面镜面散射理论和海面斜率分布理论,将海面斜率的Gram-Charlier分布应用于海面镜面散射建模,建立了以海面上10m高度风速为基准的、基于Gram-Charlier分布的海面镜面散射模型的雷达后向散射截面的计算方法.通过与实测数据的比较,验证了基于Gram-Charlier分布的海面镜面散射模型的正确性和适用性.通过仿真研究,系统总结了在不同风速、风向、极化、波段、入射角、方位向等条件下海面镜面散射的变化规律,对实际应用具有指导作用.
On the basis of the theories of the ocean surface specular-point scattering and slopes distribution and by applying the Gram-Charlier distribution of ocean surface slopes to make a model for the ocean surface specular-point scattering and taking wind speed at 10m above ocean surface as basis,we establish a calculation method for the radar backscattering cross-section of the ocean surface specular-point scattering model based on the Gram-Charlier distribution.By comparing with measured data,we verify accurac...
