摘　　要：为了提高卫星对水下隐身动目标的探测效率,对不同海况下、不同入射角度时的三维激光海面漫反射特性进行了建模仿真计算,并在实验室条件下对激光入射波动水面后产生的散射场的能量分布特性进行了的研究。首先,根据麦克斯韦尔方程和边界条件对散射场在各个方向上的分量之间的耦合关系进行了研究,并列出矩阵方程;然后,利用三维锥形波对入射激光束进行了模拟;最后,通过稀疏矩阵规则网格法求解矩阵方程,得出三维双站散射系数,并通过实验对仿真结果加以验证。结果表明该方法能够准确地表示波动水面的三维激光漫反射特性,为进一步研究三维激光海面漫反射特性奠定了基础。To enhance the detection efficiency of satellite against underwater stealth moving targets,the characteristics of the scattered field of laser from the water surface in different roughness and incident angles was studied.First,the coupling relationships among components in different directions were analyzed and the corresponding matrix equations from Maxwell equations and boundary conditions were solved with SMCG.Second,the 3D model of incident laser beam was established with 3Dtapered wave.Finally,the 3DBSC was get and verified by experiments.The results showed that the 3DBSC was enough accurate to express the characteristics of laser diffusion from water surface so that some contributions were made for the further study about the characteristics of laser diffusion from sea surface.
