| 摘 要： | 雷达的作用范围会受到诸多环境因素的影响,提出了一种地形影响下雷达作用范围三维可视化方法,该方法采样基于混合采样的雷达三维建模完成自由空间中雷达三维表现,同时引入了基于视点的模型简化方法提高绘制效率。基于几何光学法提出了一种雷达探测范围受地形影响的模型修正算法,通过插值计算地形与模型间的相对位置关系,对受地形影响的采样点进行相应修正。实验结果表明,该方法不仅计算速度快,而且能更真实、直观地表现复杂地形环境下雷达电磁信息。

| Abstract: | It is a difficult task to show visually the radar coverage, which is affected by the environmental factors. A 3D visualization method for the radar coverage under considering the terrain effect is presented. in which hybrid sampling-based method for the 3D visualization of radar coverage in the free space is used. In order to improve the rendering speed, a view-dependent simplification of model is used. Based on the principle of geometrical optics, a revised algorithm of radar model is proposed, the points ... |
