摘要
蒸发波导是发生在海洋表面的常见现象,蒸发波导的高度和强度对舰载雷达的探测距离有着重要影响。文中分析了海面蒸发波导形成机理,给出了PJ模型的详细计算公式,并根据PJ模型构建了一套蒸发波导与雷达探测威力应用软件系统,用X波段对海搜索雷达与海上配合目标进行模型验证。结果表明:根据PJ蒸发波导模型计算的波导高度与雷达实际探测距离有着一致的结果。
Evaporation duct is a common phenomenon over the oceans.The height and strength of the evaporation ducts are controlling factors for shipborn radar range and must be determined accurately to assess propagation ranges.This article discusses the cause of forming evaporation duct and offers a detailed calculation formula of evaporation duct height and evaporation duct height profiles which are taken from Paulus-Jeske(PJ) model.A computer program has been developed to calculate evaporation duct height and to pr...
