对潜用自航式声诱饵发展的有关问题进行了探讨.从潜艇防御作战的特点和对手情况出发,研究了潜用自航式声诱饵所担负的作战使命,提出了受迫式和主动式使用自航式声诱饵的概念,分析了各种反潜兵力、反潜兵器和海底反潜网所具有的反水声对抗能力,以此为基础,探索现代潜用自航式声诱饵所应具备的功能.指出了潜用自航式声诱饵应具备声学、运动和尺度三维的诱骗能力,此外,潜用自航式声诱饵还应具备固定弹道射击控制模式、实时规划弹道射击控制模式等战术使用功能. 相似文献

在我军武器装备建设逐渐"以计划为主要管理方式和手段"向"以合同为主要管理方式和手段"转变的背景下,装备采购合同管理的研究日趋深入。而装备采购合同"行政合同"的性质及合同标的物复杂性的特点,进一步凸显了标准化在保证装备采购合同规范性、降低不确定性、减少交易成本和提高工作效率中的重要作用。文章在对美军装备采办合同管理标准化特点与经验详细分析和提炼的基础上,对比我军装备采购合同管理体制及标准化现状,有针对性的提出了装备采购合同管理标准化建议,梳理了标准化重点,并为日后时机成熟时制定适用于装备采购合同管理的相关标准或指南,奠定了一定的研究基础。 相似文献

根据舰艇防空武器拦截过程的时间连续性和拦截效果的不确定性特点,提出了智能规划和优化调度相结合的舰艇防空计划生成方法。在规划阶段,先用智能规划描述语言PDDL对舰艇防空问题进行建模;针对新的来袭目标或观察的拦截结果,利用智能规划的高效行动推理能力,快速生成可能的备选行动方案;在优化调度阶段,对已生成的备选方案的行动系列进行时间、资源冲突处理,并计算选择出当前最佳拦截方案。与现有的采用离散化处理的武器-目标分配方法相比,该规划与调度过程充分体现了拦截过程的连续性,拦截效果的不确定性,拦截过程中的武器协同,以及最佳拦截时机的选择等,更好地描述了舰艇防空的实际过程。最后,通过蒙特卡罗仿真试验,验证了算法的有效性,为舰艇的自动化防空提供了一种新的解决办法。 相似文献

Ballistic missile defense (BMD) politics present an interesting evolution in how the USA, especially Congress, has come to think about BMD both as operational reality and as a symbolic policy. The argument here is that BMD's operational reality is increasingly overshadowed by its symbolic aspects. Such a status arose from rapidly changing international and domestic politics. The end result is a situation in which BMD policy in a sense floats above the question of its actual combat effectiveness. Its primary mission in part is sustaining US capacity to remain a global power and support its allies. 相似文献

The issue that this paper tackles is the assessment of the relative security benefits that Cyprus and Greece derive in the context of their cooperation on defence matters. This form of cooperation, known as the ‘Integrated Defence Space Doctrine’, aims at defending their interests in the Aegean Sea and the broader East Mediterranean theatre. The paper relies heavily on earlier research on this topic, which deals with the Greek–Cypriot alliance facing an arms race against Turkey, and uses a coefficient especially designed to assess the optimal levels of security and the associated defence expenditure of the two allies. A comparison of the relative security coefficient values for the two allies suggests that the security benefit that Greece derives thanks to its alliance with Cyprus exceeds the corresponding Cypriot benefit by far. Given the importance assigned to human resources by this index, in conjunction with the demographic problems of Greece, this conclusion justifies the recent Greek defence policy revision, emphasizing quality, capital equipment and flexibility of forces. This revision aims at satisfying the security requirements of the alliance and the increasing demands of an arms race against Turkey. 相似文献

This paper provides a methodology for estimating the economic impact of defence spending at a sub‐regional level. It does so by calculating the income and employment generated by Britain’s Royal Navy and associated defence activities in the City of Portsmouth and its surrounding area, during the financial year 2003–2004. In an era of military consolidation, the paper offers an insight into the multifaceted impact of defence‐related expenditure. Hence, it presents a generic framework that could prove useful to other researchers when seeking to measure the sub‐regional impact of naval, airforce and army facilities in other national contexts. 相似文献
