【摘要】 为了表征不同涂层表面的偏振光学散射特性,在基于微面元理论的偏振双向反射分布函数模型的基础上,针对不同涂层样品提出了一种适用范围更广的多参量偏振双向反射分布函数模型.采用遗传算法对实验数据进行模型参量拟和.实验结果表明,对几种不同的涂层样品,这种多参量模型的模拟计算结果与测量结果均能较好吻合,可以为后续的目标偏振特征提取与识别工作提供参考.更多还原

【Abstract】 In order to represent the polarization properties for different painted surfaces,a multiple parameters model which has a more wide range for use for polarized Bidirectional Reflectance Distribution Function(BRDF)based on micro-facet model is proposed.Genetic algorithm is used to get the key parameters in the model.The comparision show that the simulation results agree well with the experimental data and can be used as a reference for target polarization feature extraction in the future.更多还原
