| 摘 要： | 为了解决激光在海战中的应用瓶颈问题，采用基尔霍夫近似的方法对激光海面漫反射特性进行了研究。通过对激光光束入射海面后产生的散射场的分析、计算，并采用遮蔽函数对计算过程中的阴影效应加以修正，得出了较为准确的二维激光海面双站散射系数。最后通过分析，得出了海面粗糙度、入射角度与激光漫反射率之间的关系，为相关的研究提供了一定的理论依据。

| Abstract: | Aiming at the bottleneck problems of laser applications in the sea battle, the characteristics of laser diffusion from sea surface is studied with the method of Kirchhoff Approach. The more accurate backscattering coefficient and bistatic scattering coefficient are derived by analyzing and computing the laser scattering field from the rough sea surface and by modifying the shadowing effect in the process of computation using shadowing function. Finally, the relationship between the roughness of sea surface, incident angle and the laser diffusion reflectivity is obtained and some results can be taken as the theoretical basis for other relevant studies. |
