摘要
针对地形、地物会形成雷达探测盲区的问题,给出一种实现地形影响条件下雷达电磁波可视化方法。基于雷达方程,对自由条件下雷达三维探测范围建模;利用几何光学法对电磁传播进行模拟,绘制出地形遮挡下雷达的实际探测范围;并利用OpenGL进行曲面绘制,实现地形影响条件下雷达电磁波的三维可视化。该技术可为雷达装备的部署、训练等提供支持。
The topography and terrain cause radar detection blind zone, introduce a method of radar electromagnetic wave visualization under influence of topography. Based on radar equation, establish modeling of radar 3D detection area under free conditions. Then, use geometrical optics to simulate electromagnetic propagation, draw the radar actual detection area by terrain masking. At last, use OpenGL to carry our curve drawing, realize 3D visualization of radar electromagnetic wave under influence of topography. The technique can provide the support for the deployment of radar equipment, training etc.
