摘要 为研究粗糙海面对高频地波雷达的影响,本文首先引入了更符合实验结论的粗糙海面相干谱反射系数的修正公式,并将其代入到雷达方程,计算了高频雷达地波空间场分量的传播损耗。本文所预期的结果符合架设于海岸的高频地波雷达的实际环境。 To study the influence of rough sea surface on the space field of HF ground wave radar on coast, a derivation of the reflection is introduced first, which is suitable for rough sea surface with Gaussian distribution of heights, and then the reflection is substituted into the radar equation, finally, the propagation loss over rough sea surface is calculated. The resulting predictions in this paper are more accurate and realistic.
