二维激光海面漫反射能量分布特性

Two dimensional energy distribution characteristics of laser diffusion from sea surface

针对激光点对点通信方式的不足,根据实战需要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,并且采用前后向迭代的数值方法结合格林函数谱加速算法对激光海面漫反射通信的能量分布特性进行了研究.通过仿真计算和实验验证,得出了二维激光海面双站散射系数,并对激光光束入射海面后的散射场进行了分析.结果表明:入射激光束经过粗糙海面散射后,能量大部分集中在前向散射区域上,而后向散射强度很弱,并且在散射场的边缘处能量迅速衰减,说明激光海面漫反射组网通信方法是可行的.

Idea of building the communication networks by laser diffusion from sea surface was proposed according to the requirement for real sea battles.The energy distribution characteristics of scattered field were studied using forward-backward iteration combined with green spectral acceleration algorithm.The accurate two dimensional laser bistatic scattering coefficients from sea surface were obtained and the results were verified by experiments.The results show that the energy scattered from the sea surface is concentrated in the forward zone,while the backscattering strength is weak,and which attenuates fast in the edges of the scattered field.The feasibility of building communication network by laser diffusion from sea surface among vessels is illustrated.
