摘要
针对激光点对点通信方式的不足,提出了利用海面作为激光漫反射媒介进行组网通信的设想,并对激光入射理想导体表面后产生的散射场进行了的研究。首先利用三维锥形波对三维入射激光束进行了模拟;然后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;最后通过结合格林函数谱积分加速算法的前后向迭代法求解矩阵方程,得出三维散射系数,准确的表示了基于理想导体界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。
Aiming at the shortcomings of laser point to point communication, the assumption of building the communi cation networks by laser diffusion from sea surface is proposed so that the characteristics of the scattered field of laser from the PCS is studied. Firstly, the 3D model of incident laser beam is established with 3D tapered wave. Secondly, the coupling relationships among components in different directions are analyzed and the corresponding matrix equations are calculated with FBM/SAA. Finally, the 3D BSC is given to accurately express the characteristics of laser diffusion from the PCS. That will make contribution for the further study about the characteristics of laser diffusion from sea surface.
