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3维标量锥形波对入射激光束进行了模拟；然后列出了积分方程，并根据矩量法进行了离散；最后通过前后向迭代法求解矩阵方程，得出了3维散射系数，准确地表示了基于理想导体界面的3维标量激光漫反射特性。Abstract: Aiming at the shortcomings of laser point-to-point communication, the assumption of constructing communication networks by laser diffusion from sea surface was come up with, and the characteristics of the scattered field of laser from perfect conductor surface(PCS) was studied. First, the 3D model of incident laser beam was established with 3D scalar tapered wave. Second, the matrix equation was given and discretized with the method of moments. Finally, the 3D bistatic scattering coefficient was obtained with forward-backward method to accurately express the 3D scalar characteristics of laser diffusion from PCS.
