摘　　要：研究了蒸发波导环境中雷达对海面舰船目标的最远探测距离预报模型.现有雷达超视距探测距离预报模型的预报结果往往偏离实际雷达观测值,分析了现有预报模型的不足,提出利用高度上多个散射中心来描述海面舰船目标,通过引入目标雷达散射截面积高度分布模型来对现有模型进行修正,并与实际观测数据进行了比较,证明修正后的预报模型的预报结果与观测值更接近,预报准确度更高.The prediction model of the radar maximum detection range of the sea surface ship in evaporation duct environments is studied. The predictions of the present radar Over The Horizon detection range prediction model frequently deviate significantly from radar measurements. The limitation of the present prediction model is described. The use of the vertical multi-scatter center to model the surface ship is presented. A vertical distribution model of the radar cross section is used to correct the present prediction model. Finally, the predictions by the corrected model are compared with the radar observations. The result shows that the predictions by the corrected model agree well with the observations and are more accurate.
