Abstract:

The survivability of defense system refers to the ability of the system to maintain or restore its defense performance to an acceptable level when the system is facing enemy attack damage or its own node failure. In order to measure and characterize the survivability of defense systems with different architectures， based on the combat confrontation scenario and from the ability of the system to build strike links， a new method of survivability measurement of defense systems is proposed. This method can be used to quantitatively characterize the survivability of traditional defense system and distributed defense system， and provide support for further distributed defense research and high survivability architecture design of defense system.

Key words: defense architecture, survivability measurement, strike link, node survival probability, distributed defense system

摘要：

防御体系抗毁伤能力是指在体系面临敌袭损伤或自身节点失效的情况下，体系维持或恢复其防御性能到一个可接受程度的能力。为了对不同架构防御体系的抗毁伤能力进行度量表征，基于作战对抗场景，从体系所能构建打击链路的能力出发，提出一种防御体系抗毁伤度量的新方法。可依据此方法对传统防御体系及分布式防御体系的抗毁能力进行量化表征，为进一步开展分布式防御研究及防御体系高抗毁性架构设计提供支撑。
