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。
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.
一些科学家甚至提出，可以用这种GPS的扰动来追踪海啸在开阔海面上的传播。
Some scientists have even proposed using such GPS disturbances to track tsunamis in the open sea, Okal added.
在深海水域，海啸的传播速度像喷气式飞机一样快，但在海面看到的波浪不大。
Tsunamis travel as fast as jet aircraft in deep water, where they are spread over a far deeper water column and make for smaller and very gradual waves at the surface.
