基于统计模型的二维空间相关海杂波的快速仿真

Rapid Simulation of 2-D Spatial Correlated Sea Clutter Based on Statistical Model

基于概率密度函数和相关函数等统计特性,提出了一种模拟二维空间相关海杂波的统计模型。数值比较表明,统计模型和电磁散射模型模拟的海杂波的纹理特征、自相关函数和PDF吻合较好,此外,该统计模型效率高,可用于模拟大场景二维空间相关的海杂波。

Based on the statistical properties such as probability density function,and correlation function a statistical model to simulate the spatial correlated two-dimensional(2-D)sea clutter is presented.The comparisons show that the texture feature,autocorrelation function and PDF of the sea clutter simulated by the statistical model have a good agreement with the results given by the EM model.Furthermore,the statistical model is with high efficiency and can be used to simulate the 2-D spatial correlated sea clutter in a larger scene.
