粗糙表面相关结构对远场散斑相位差统计性质的影响

Effects of Correlative Structure of Rough Surface on the Conditional statistical Distributions of Phase Difference for Gaussian Speckle in Far-Field

假设弱散射作粗糙表面高度起伏服从高斯统计，在表面高度起伏分别服从高斯相关、指数相关、圆型相关的情况下，分析了由弱散射体产生的远场高斯斑场相位差的条件统计分布。

The Gaussian random variable is assumed for the height variation of rough surface of weak diffuser. The conditional statistical distributions of phase difference for Gdussian speckle produced by a weak diffuser in the far-field is discussed in the case that the height variation of rough surface obeyes Gaussian correiation, exponential correlation and circle correlation respectively.
