侦察无人机作战效能评估准则研究*

在对有人驾驶飞机作战效能评估方法的分析研究基础上,提出了完整的侦察无人机作战效能评估指标体系。建立了作战效能的评估准则与数学模型,并对影响侦察效能的参数进行了分析。运用该方法对“全球鹰”和“捕食者”两种无人机的侦察效能指数进行了定量评估,结果验证了该评估准则的可用性。     

Hilbert谱分析和平稳度

提出了本征模式函数IMF成员相应的幅度及频率时间函数的计算方法。由函数的Hilbert谱可获得相关的边缘谱,边缘谱确定了几乎连续的能量分布,从而提供了通过每个频率值测量总能量的方法。根据能量-频率-时间分布,就可以定量确定平稳性,平稳性是物理过程的一个复杂属性,其由平稳度DS和统计平稳度DSS进行度量,同时给出了DS和DSS的计算公式。

Cyber-weapons in nuclear counter-proliferation

ABSTRACT

Under what conditions are cyber-weapons effective in nuclear counter-proliferation? With continued interest in nuclear proliferation professed by Iran, North Korea, and Saudi Arabia, a discussion of the effectiveness of counter-proliferation measures remains relevant. Cyber-attacks as military option in a state-on-state conflict still requires additional corroborating evidence to make conclusions about its long-term effectiveness. This work analyses the general applicability of cyber-weapons and their usefulness in nuclear counter-proliferation. Through a comparative case study of Operation Orchard, Stuxnet, and recent “Left-of-Launch” operations against North Korea, the essay finds that cyber-operations are not particularly effective against nuclear programmes that are in the later stages of their development. They can disrupt and delay a nuclear programme temporarily, if the attack remains clandestine, but cannot halt nuclear proliferation all together. However, effectiveness increases if they are used in combination with conventional weapons. The article addresses a topic of interest to national-level decision-makers: whether cyber-operations can and should play a role in nuclear counter-proliferation.
