雷达对抗侦察装备作战能力的ANP幂指数评估方法

针对雷达对抗侦察装备综合作战能力对电磁环境的依赖性,提出一种基于网络层次分析法(Analytic Network Process,ANP)的雷达对抗侦察装备在不同电磁环境下作战能力的幂指数评估方法。通过对雷达对抗侦察装备作战任务及复杂电磁环境下的表现进行分析,确定装备作战能力指标;利用ANP分析各指标间的相互关系,计算出指标相对的权重;把该权重作为各指标的幂指数,计算雷达对抗侦察装备在不同电磁环境下的作战能力指数;最后结合某型装备多次不同环境下试验的数据,对该装备的综合作战能力进行评估。     

用于卫星干扰源定位的压缩感知DOA估计方法

针对传统测向方法的实际应用性能较差,提出一种基于压缩感知(CS)的卫星干扰源定位方法。根据干扰信号方位角的空间稀疏性,建立了压缩感知波达方向(DOA)估计模型。通过协方差矩阵的高阶幂逼近信号子空间和矩阵的共轭对称特征,利用高阶幂矩阵的主对角线下左下角列向量进行波达方向估计。仿真实验验证,该方法不需要已知干扰源数,具有较高的精度和较好的分辨力,且能满足对相干干扰信号的估计。对压缩感知DOA估计在卫星干扰源定位中的应用具有一定参考意义。     

Land power in the age of joint interdependence: toward a theory of land power for the twenty-first century*

This essay outlines a theory of land power. After explaining the absence of such a theory, the article establishes the modern context for such a theory, specifically within the concept of joint interdependence. The analysis defines key terms and premises behind the theory, to include a definition of land power. The argument then outlines the national elements of power that contribute to a theory of land power. The analysis next applies the theory to the fundamental purposes of military power: defeat, deter, compel, assure, shape and support to the nation. The analysis then tests key definitions, supporting premises, and utility of the theory. The essay argues that historical experience validates the applicability and utility of the theory, and offers a solid basis for extrapolating the validity of the theory into the near future.     

Air power in humanitarian intervention: Kosovo and Libya in comparative perspective

It would be hard to overstate the importance of air power in humanitarian intervention (HI) and the Responsibility to Protect (R2P). Yet, the role of air power in HI and R2P has been understudied. This article seeks to remedy the lack of systematic investigation. It does so by developing a framework for assessing the effectiveness of air power during military operations in HI and R2P and applies it to NATO’s air campaigns in Kosovo (Operation Allied Force) and Libya (Operation Unified Protector). Upon examination NATO is revealed to have fared better in Libya than Kosovo in positively accomplishing its stated humanitarian objectives, minimizing collateral damage and reducing the costs for the interveners, all of which are aspects considered by the model. The relative effectiveness of Operations Unified Protector is generally attributed to geography, diplomacy and technology. It is argued that better ground support, unmanned aerial vehicles (UAVs) and burden sharing are needed to enhance the utility of air power in HI and R2P even further.     

基于RLC振荡电路电磁超声换能器激励研究

根据目前电磁超声的基本理论以及现有的激发方式，在EMAT基本模型基础上，应用新型开关电源IG—BT代替交流接触器优化激发电路系统，旨在提高电磁超声换能器的磁声转换效率，解决其灵敏度低以及热效应的不良影响等问题。通过实验对系统优化前后的数据进行比较，表明优化后的系统不仅降低了能耗，而且提高了原有交流接触器作为开关时超声幅值和转换效率。     

舰船推进系统液力偶合器滑差变化规律分析

研究了将液力偶合器滑差特性用于舰船推进系统稳态特性分析和机-桨联控曲线设计,由此发现滑差变化规律.分析了两种正常工况和五种应急工况下的"船-桨-机"匹配稳态特性以及用液力偶合器滑差所做的主机负载判别.有关滑差的主要研究结果有:按螺旋桨特性工作时,液力偶合器滑差的大小既取决于船体阻力特性(它决定了螺旋桨负载特性),又受液力偶合器自身的"效率-转速"相关性(运转特性)的影响.     

Military Expenditure as a Proxy for State Power. The Case of France

This paper attempts to build a simple indicator of state power. Military expenditure is the paper’s point of departure, with the definitions given by NATO, SIPRI and others. This definition is discussed and a power version is build, using French budgetary data. Then a defence of the result against traditional or non-traditional critics is presented under an imperative of action. Finally, this concept is enlarged and a new concept of power expenditures is given, one more time using French budgetary data. The conclusion is that this large expenditure concept is an unbiased but imperfect indicator of the will to act, and has to be completed by GDP to indicate the capability to act in the long-run.

炮兵火力任务分配的优化模型

现代作战,参战兵种多,炮兵的火力单位和类型更为复杂,不同的火力单位具有不同的毁伤效果,如何用最小的代价取得最大的军事效益,是一种火力任务分配的优化问题.根据不同炮种和目标的特点,建立在一定约束条件下的炮兵火力任务分配模型,并将其转化为指派问题,运用匈牙利算法求解,达到优化分配火力任务的目的.通过仿真计算证明这是辅助指挥员进行射击决策的一种有效手段,为作战指挥理论提供了一种新的数学模型.     

The EU Global Strategy and diplomacy

The new EU Global Strategy has significant implications for EU diplomacy, in terms of both goals and means. This article first analyses the timing of the strategy as an exercise in diplomacy in its own right. Second, it argues that the strategy outlines a more expansive and noticeably more smart power-oriented approach to diplomacy in practical terms. Finally, it notes that the strategy has a new meta-narrative for EU diplomacy, which seeks to project a blend of both realistic assessment and idealistic aspiration.
