摘　　要：低空突防越来越成为人们关注的热点。在研究低空突防过程中,雷达探测是一个不可忽略的因素。必须知道在某高度、某距离上雷达是否可以探测到,才能更好的进行低空突防和防御低空突防。在上述需求和目前研究现状基础前提下,结合雷达目标截面积得到雷达自由空间探测范围和数字化地形高层数据的基础上,利用光的直线传播原理计算得出雷达在任意海高和真高平面上的探测范围。最终在VC++6.0下实现并测试可行,从而为研究低空突防提供依据。Low altitude penetration is becoming the hotspot which people pay more and more attention to. In the research on low altitude penetration, radar detection is an essential element. After confirming that whether radar could detect something in some height and length, could do better in the low altitude penetration and defense pene- tration. Considering the demand above and current research, the radar range of the free space and Digital Terrain Elevation Data （DTED） by combining the Radar Cross Section （RCS are achieved）. The radar detection range of any height including MSL and AGL by using the method of optics principles is visualized. In the end, this algo- rithm is achieved in VC ＋＋ 6. 0 which could provide the foundation for low altitude penetration.
