摘要
雷达波在近海面传播时受到各种因素的影响,使得雷达探测出现异常现象,尤其在蒸发波导条件下,会形成波导传播。文中描述了通过气象水文信息得到蒸发波导折射率剖面,再由电波传播模型和修正的雷达方程估计出雷达在蒸发波导条件下的作用距离。并通过试验,初步验证了上述方法。
There are all kinds of factors can affect radar electromagnetic wave when it propagating in the atmosphere. They can result radar detect singularly. And there will be a duct-propagation in the condition of evaporation duct. This paper describe how to getting refractive index section using meteorologic data. And then get radar detection range in the condition of evaporation duct by propagation model and modified-radar equation. In the end of the paper, validate the way discussed by the experimentation in Hainan.
