摘　　要：文章综合SRTM3地理高程数据和实测的高于雷达馈源海拔建筑物、风力发电机等地理信息数据,计算不同高度水平面雷达覆盖率,选定0.5°~2.5°(间隔0.5°)不同仰角下360°范围遮挡百分比,用于分析评估新一代天气雷达探测环境。将该研究方法应用于陕西定边新一代天气雷达选址环境分析中,通过数据质控筛选和GIS技术融合数据处理,计算不同候选站间探测环境评估结果,综合地形和高大建筑物遮挡等因素,分析评价不同拟选站间雷达探测环境。This paper synthesizes SRTM3 geographic elevation data and measured geographic information data of buildings and wind turbines above radar feed altitude.The radar coverage at different heights is calculated.The occlusion percentage of 360° range at different elevation angles of 0.5°~2.5°(interval of 0.5°) is selected to analyze and evaluate the detection environment of new generation weather radar.The research method is applied to the site selection environment analysis of the new generation weather radar in Dingbian,Shanxi Province.Through data quality control screening and GIS technology fusion data processing,the evaluation results of detection environment between different candidate stations are calculated.Considering the factors such as terrain and high building occlusion,the radar detection environment between different proposed stations is analyzed and evaluated.
