| 摘 要： | 为研究粗糙海面和粗糙海面上刃形峰对海岸雷达波传播的影响，在粗糙海面和刃形峰衍射损耗公式中引入了更符合实验结论的粗糙海面反射系数，并用来计算雷达波在粗糙海面(含刃形峰)的传播衍射损耗。结果表明来自粗糙海面的反射是计算雷达波沿粗糙海面传播损耗和刃形峰对雷达波衍射损耗的不可忽视的重要因素。

| Abstract: | To study the influence of rough sea surface and a knife-edge on coast radar wave propagation, a reflection coefficient is introduced, which is suitable for rough sea surface, and substitute it into the propagation loss formula for rough sea surface and for a knife-edge, respectively. The results show that reflection from rough sea surface is an important factor in calculating propagation loss over rough sea and a knife-edge in the presence of rough sea surface. |
