摘　　要：为了研究蒸发波导条件下雷达天线高度和仰角对探测距离的影响,利用基于蒸发波导的雷达探测距离预测方法,仿真计算了不同大气层结条件下,天线仰角和高度分别取不同值时的雷达探测距离。仿真结果表明天线仰角和高度对雷达探测距离影响很大。相同条件下仰角为0°时探测距离最大,雷达探测距离不是单调地随天线高度的增加而增加或减小,存在一个最佳天线高度,能大大增加雷达探测距离。In order to research into the influence of radar antenna altitude and elevation on the detec-tion range in the condition of evaporation wave-guide, this paper uses the predicting method of ra-dar detection range based on evaporation wave-guide, simulates and calculates the radar detection ranges at different antenna altitudes and elevations in the condition of different atmospheric strati-fications. The simulation results indicate that the influence of antenna altitude and elevation on ra-dar detection range is obvious. In the same conditions, the detection range is the biggest when the antenna elevation is equal to 0°. The radar detection range does not monotonously increase or de-crease along with the antenna altitude increases. There is an optimal antenna altitude, which can greatly increase the radar detection range.
