一种新的系统生存性量化分析方法

摘要

信息化战争条件下,雷达组网系统面临着严峻的"舒特"攻击.通过将攻防过程描述为拟生灭过程,对系统建立了数学模型,定量地来刻画系统所面临的安全威胁,并给出重要性能指标的计算方法.数值分析结果证明了模型的正确性,对于定量分析雷达组网系统生存性提供了一种新思路.%Under the condition of information warfare,the radar network system confronts serious"Sutter"attack. By describing the offensive and defensive process as a quasi-birth-and -death process,a mathematical model is established to quantitatively describe the security threats faced by the system,and the calculation method of the important performance index is given. The numerical analysis results show that the general analytical model is correct,and it provides a new idea for the quantitative analysis of radar network survivability.
