摘　　要：蒸发波导环境中电磁波传输特性与自由空间不同,给雷达的探测性能带来了很大影响。建立了基于蒸发波导环境的传输损耗和射线轨迹模型,分析了其对雷达探测性能、测角精度和测距精度等方面的影响,为雷达探测性能的评估和修正提供了参考。Electromagnetic wave transmission characteristics in evaporation duct environment and in free-space are different,which makes a great impact on radar detection performance. This paper es- tablishes transmission loss and radial track model based on evaporation duct environment, analyzes its influence on radar detection performance, angle measurement precision, range measurement pre- cision, etc. ,which provides reference for evaluation and revision of radar detection performance.
