摘要
提出了一种复杂环境影响下的雷达探测范围三维可视化方法。该方法以雷达方程为基础,主要考虑地形和电磁干扰影响下的雷达探测范围三维可视化。首先利用均匀采样法建立自由空间中的雷达探测范围模型,然后在获取数字地形高程的前提下,基于光的直线传播原理提出一种雷达探测范围受地形影响的算法,并实现了地形影响下的雷达探测范围三维可视化;以干扰方程为基础,实现了多干扰源情况下雷达探测范围三维可视化。利用基于视点的雷达模型简化方法,有效地提高了绘制速度。实验结果表明,该方法不仅效率高,而且能真实直观地展现雷达探测范围。
A method about 3D visualization of radar detection range in complicated environment is presented.Based on the formula of radar,this method considers the influence of terrain and electronic jamming.First,a radar detection range model in the free space is built by using uniform sampling method,and then according to the terrain elevation around the radar,an algorithm of 3D visualization of radar detection range is proposed to represent the 3D radar detection range affected by terrain.Based on jamming formula,the radar detection range considering the influence of multi-electronic jamming is implemented.Besides,by using view-dependent simplification of model the speed of rendering is improved.The result of experiment shows that this method not only is efficient but also can visualize radar detection range.
