| 摘 要： | 针对激光点对点通信方式的不足，根据舰艇编队通信的实际需要，提出了利用海面作为激光漫反射媒介的一对多的组网通信方法，并且采用基尔霍夫近似的方法对激光海面漫反射通信的特性进行了研究。通过对激光光束入射海面后产生的散射场的分析计算，采用遮蔽函数对计算过程中的阴影效应加以修正，得出了较为准确的2维激光海面双站散射系数和后向散射系数，并进行了实验验证，说明了激光海面漫反射组网通信方法的可行性。 |

| Abstract: | The character of network communication by laser diffusion from sea surface was studied by Kirchhoff approximation. The backscattering coefficient and bistatic scattering coefficient were derived through computation of laser scattering fields from two-dimensional rough sea surface according to stationary phase method and optical geometry approach. And the shadowing effect was modified by shadowing function in the process of computation. The results were validated by experiments, showing the feasibility of network communication by laser diffusion from sea surface． |
| Keywords: | diffusion Kirchhoff approximation bistatic scattering coefficient shadowing effect |
