| 摘 要： | 为了准确评估武器装备在战场电磁环境中的作战效能，从定量分析的角度，采用三维矢量抛物方程方法建立电磁环境仿真模型，通过Kriging算法对地形高程进行插值，在理想边界条件下，分析了远距离不同高度的电磁波衰减特性，并与二维抛物方程计算结果进行比较。结论表明，电磁环境仿真模型能够给出战场电磁环境的基本数据，计算精度较高。

| Abstract: | In order to accurately evaluate weapon operational effectiveness in combat electromagnetic environment, the electromagnetic environment simulation model is set up by three-dimensional vector parabolic equation method. Based on regular grid elevation data, Kriging method is used to obtain the interpolation data. With the perfect boundary condition, the electromagnetic propagation loss for different range and height is obtained by assuming forward propagation. Comparison is shown with two-dimensional parabolic equation, and results are accurate and valid. |
