摘　　要：通过分析雷达探测范围边界与数字地形高程的相对位置关系,提出一种基于几何光学原理的雷达探测范围受复杂地形影响的修正算法。采用雷达传播衰减模型和混合采样方法,应用该修正算法,实现了对复杂地形影响下雷达探测范围的修正。实验结果表明,该算法不仅对复杂地形适应性强,而且表现效果真实直观。Through analysis of the relative position between the borderline of radar coverage and the height of digital terrain, the correction arithmetic of radar coverage influenced by complicated terrain was proposed, which is based on the principle of geometrics optics. Finally, the correction of radar coverage in complicated terrain was realized, which uses the propagation attenuation theory of the radar electromagnetic wave, the method of mixed sampling and the correction arithmetic. The result of experiment shows that this method not only is efficient for the complicated terrain, but also can make the visualization lifelike.
