摘　　要：根据巡航导弹巡航段飞行特点模拟导弹三种不同巡航高度时的巡航航迹,仿真导弹RCS序列随时间的变化情况,考虑导弹低空突防时面临的强地杂波战场环境,估算出地杂波信号强度,仿真计算导弹在三种巡航高度下突防时雷达的探测概率。结果表明:巡航导弹低空突防时,地杂波的强度很大程度上制约了雷达的探测效能,巡航高度越低,雷达探测效能越差,越有利于导弹突防。According to the flight feature of cruise missile in cruise phase, this paper firstly simulated cruise paths in three different flight altitudes, and then calculated the change of actual RCS series. Signal intensity of land clutter was estimated because battlefield condition with intense land clutter was taken into consideration when missile adopted low altitude penetration. At last radar detection probabilities of three cruise altitudes were calculated. The results indicate that the lower cruise altitude for cruise missile, the weaker detection capability of radar will be, and the more benefit for missile penetration. Meanwhile, the intensity of land clutter restricts the efficiency of radar detection in great degrees.
