摘要
海面上受水蒸气的影响容易形成大气波导,造成电波的超视距传播影响雷达探测;基于抛物方程模型分析了海面蒸发波导环境下电波传播的特性,分析了蒸发波导高度、发射天线高度等对电波传播损耗与雷达探测距离的影响。
The ducting is easy to form over sea because of the impact of vapor,which causes the radio wave propagation beyond visual range and influences the radar detection.The radio propagation characteristics are analyzed by using the parabolic equation model in evaporation duct environments over the ocean,then the influence of the evaporation duct heights and the antenna heights on the propagation loss and radar detection range are analyzed.
