【摘要】 利用蒸发波导效应实现舰船雷达超视距探测是扩大其作用范围的有效方法之一。针对蒸发波导实际测量困难的现状，利用预测模型对蒸发波导剖面进行描述是较好的实用方法。通过对常用单参数预测模型、双参数预测模型和三参数三种蒸发波导预测模型在大气修正折射率剖面描述、对雷达电波射线描述等情况与实测蒸发波导参数的比较，证明了在描述蒸发波导剖面和利用蒸发波导参数进行电波传播分析等方面，双参数预测模型都具有较好的精度。更多还原

【Abstract】 The evaporative waveguide effect is one of the effective methods to enlarge the range of radar detection. The prediction model is a good method to describe the profile of the evaporative waveguide. Through the comparison of the three evaporation waveguide prediction models(Single parameter model, double parameter model and three parameter model) with the measured evaporation waveguide parameters in the description of atmospheric modified refractive index profile and radar radio ray, it is proved that the two parameter prediction model has good accuracy in describing the evaporation waveguide profile and analyzing the radio wave propagation by using the evaporation waveguide parameters.更多还原
