摘　　要：简要分析了雷达脉冲电波环境。针对准确预测雷达脉冲电波在不规则地形与复杂大气条件下的衰减特性这一问题,提出了一种雷达脉冲电波环境构建方法。该方法基于抛物方程、数字高程模型,通过卷积加和抛物方程计算得出的雷达脉冲频谱电波场,能够科学地预测在实际地理环境与复杂大气条件下的雷达脉冲电波衰减特性。应用该方法基于福建沿海某地实际地理环境与气象条件进行了仿真实验,实验结果与电波传播理论吻合。得出结论:该方法具有科学性与实际应用价值。Radar pulse radio wave environment was briefly analyzed.To the difficult question of accurate prediction radar pulse radio wave＇s loss characteristic in rough terrain and complicated meteorological circumstance,a method of construction radar pulse radio wave environment was put forward.By way of convolve parabolic equation produced monochromatic wave fields with the radar pulse signal spectrum,this method based on parabolic equation and digital elevation model could scientifically predict radar pulse radio characteristic in the condition of rough terrain and complicated meteorological circumstance.A simulation based on true Fujian some area＇s geographical environment and meteorological circumstance was done by means of this method.The simulation results are consistent with radio wave propagation＇s theory.The simulation＇s conclusion is that this method is of science and practical application value.
