摘　　要：在低空突防作战中,防空系统对重要位置提供完全封闭的保护,进攻飞机需要穿越防空体系,如何提高飞机在威胁区的生存概率是当前研究的重点。在考虑地形遮蔽的基础上,建立雷达探测模型;综合考虑飞机在威胁区运动过程中RCS(Radar Cross Section)的变化,得到雷达探测概率指标;结合飞机在威胁区突防时间指标,构建了突防方向函数模型,并根据任务选择不同的突防方向。为配合飞机更好地执行作战任务,通过对雷达实施压制干扰,有效减小了雷达威胁等级。仿真结果表明,选择特定的突防方向,能提高飞机的生存概率;配合支援干扰,能使飞机避开雷达威胁,提高飞行器低空突防能力。In low altitude penetration combat, air defense system provides completely closed protection to important position, and how to increase the survivability of fighter plane when crossing the threatening area is the key-point in current research. We established a radar detection model based on radar terrain masking blind space. Considering the change of Radar Cross Section（RCS） of the aircraft during its movement in the threatening area, we obtained the radar detection probability. On which basis and the penetration time index, the penetrating direction function was established ,and penetrating direction was determined according to the different missions. To enhance the survivability of airplane, blanket jamming was implemented to decrease the threatening of radar. The result of the software simulation demonstrates that selecting a specified penetrating direction and using blanket jamming will enable airplane to avoid radar threatening detection and improve the survivability of it.
