基于层次分析法的舰舰导弹武器系统作战环境指数研究

针对海况、大气波导、海浪杂波等环境因素对舰舰导弹武器系统作战效能的影响,采用层次分析法构建了舰舰导弹武器系统作战环境指数的层次结构,同时量化了各目标层的有关因子,确定了各目标层的权重,并建立了舰舰导弹武器系统作战环境指数的评估方法。经算例分析表明:该方法能够评估复杂环境条件对舰舰导弹作战效能的影响,为舰舰导弹的作战使用提供辅助决策支持。     

性能优良的尖端武备

虽然自上个世纪80年代以来，韩国海军的主力作战舰艇大都是在本土设计和建造的，但是舰上的武器，包括舰舰导弹、舰空导弹及鱼雷等无不是美国、法国或德国的产品，不过这种状况即将改观。近年来，纷纷登场亮相的“韩流武器”引起世人的极大兴趣，如新型水面舰艇和潜艇、超音速教练机、各种类型的导弹、主战坦克及装甲车辆等。其中，海军武器装备除各型舰艇外，舰对舰导弹、反潜导弹、     

超视距目标指示位置对舰舰导弹目标捕捉概率的影响

超视距目标指示是中远程舰舰导弹作战运用的基础。在分析目标指示数据误差形式的基础上,根据超视距目标指示的原理和舰舰导弹解命中原理和寻的雷达捕捉目标的原理,建立了基于指示站位置的超视距舰舰导弹目标捕捉模型,采用Monte Carlo法对模型进行仿真,结果表明指示站位置对舰舰导弹捕捉概率有明显的影响,得到了求取指示站合理位置的方法,该方法对提高中远程舰舰导弹的作战运用效率有指导意义。

跨世纪反舰导弹新一族

冷战时期,舰对舰导弹的设计侧重于能够在远洋和蓝水水域作战,要求具有超视距攻击能力。目前,侧重点已转向提高沿海和黄水区域作战能力。这种转变导致导弹向远射程、超音速、高命中精度方向发展,并且成为各国海军发展反舰导弹的共同选择。美国美国海军已经制定了对舰载AGM-84“鱼叉”反舰导弹进行改进的计划,以提高其对陆攻击能     

舰舰导弹攻击样式选择的决策分析

根据舰舰导弹攻击时使用雷达方式的不同,可将舰舰导弹攻击主要归结为三种样式,即其他兵力引导攻击样式、被动雷达攻击样式和主动雷达发波攻击样式。衡量各个攻击样式优劣主要考虑攻击的隐蔽性、命中率和发挥武器最大射程等三个因素。为此建立舰舰导弹攻击样式选择问题的递阶层次结构模型,从衡量各攻击样式优劣的三个主要因素出发,对模型进行了分析。最后得出了以其他兵力引导攻击为最佳攻击样式的结论。     

眼位影响下着舰信号官指挥战位位置

着舰信号官眼位直接影响其对舰载机状态的观察和判断,恰当的着舰信号官指挥战位位置有利于着舰过程中对舰载机飞行员的正确指挥、引导和控制,保障着舰回收作业安全实施。针对俄罗斯现役“库兹涅佐夫”号航母,建立着舰信号官指挥战位位置所对应的着舰信号官眼位和视角数学模型,并结合人眼最小分辨角,针对着舰信号官指挥战位位置在全甲板范围内进行仿真分析。仿真结果表明,从着舰下滑道入口点到着舰信号官决策点过程中,着舰信号官视角变化趋势保持一致,在满足视角差阈值条件下,理想着舰信号官眼位随着着舰指挥战位在甲板上位置的变化具有明显的分布规律,应将其纳入航母着舰信号官指挥战位设计的影响因素,并为其在航母甲板上位置的合理设置提供有益参考。

Panjwai: a tale of two COINs in Afghanistan

The US Army has two approaches to counterinsurgency operations in Afghanistan. One is hard, or combat-focused, and the other is soft, or development-focused. This study examines two US Army task forces deployed to Panjwai District, Afghanistan from 2012 to 2013. CTF 4-9 and 1-38 offer a meaningful comparison because they pursued these contrasting approaches among the same population and against the same enemy at the same time and place. The study compares each unit’s approach and finds that neither approach was successful absent the other. The article concludes by recommending further research into combining the approaches at the operational level.

Forecasting a Hurricane: Israeli and American Estimations of the Khomeini Revolution

The surprising ‘Arab Spring’ raises the question as to what would enable national intelligence to provide high quality warnings prior to the eruption of popular revolutions. This article uses new sources of evidence to trace and explain Israel's success in comparison to US failure at correctly estimating the course of the Iranian Revolution in 1977–79. In explaining this variance, the article shows that it was mainly the result of the intimate acquaintance of Israel's representatives in Iran with the local language, history and culture, as well as the ability to communicate with locals – tools which the Americans completely lacked.     

关于教师继续教育培训模式的思考

继续教育作为终身教育的重要组成部分和基本形式,对教师的发展成长意义重大。继续教育工作开展十多年来,取得了一定的成绩,但还存在不少问题,如学习动机较为被动,管理认识不到位,教学内容陈旧空泛,教学方法呆板机械等。随着课程改革的不断深入,继续教育必须采取相应的改进措施,树立以人为本,服务至上的观点,教学内容的前瞻性与实用性并重,教学人员进行整合,教学方法灵活多样,评价考核规范科学等,以此激活受训教师内在的学习动机,更大程度地提高继续教育培训的实际效果。

Interpreting the Ribchester Helmet

In 1796 a 13-year-old boy playing on wasteland behind his father’s house in Ribchester, Lancashire discovered an assemblage of over 30 Roman artefacts, including a decorated brass helmet. Although partially corroded the Ribchester helmet is a fine example of a first-century AD cavalry sports helmet. This article considers how the interpretation of the helmet has evolved since its discovery. The multi-faceted iconography of the helmet with its mural crown diadem is that of an elite soldier and is paralleled in other examples of cavalry sports helmets of the Ribchester type. The long-neglected imagery on the helmet bowl is reinterpreted and seen not as a haphazard collection of randomly placed combatants but as a highly structured, symmetrical composition specifically designed to be viewed from different directions.     

Putin – the masked nemesis of the strategy of ambiguity

Recent events demonstrate the complex and adaptive approach employed by Russia to reassert influence in Europe. The changing face of Russia’s strategy commenced in 2007 when it launched a crippling cyber-attack against Estonia. This was followed by a large Russian conventional attack against Georgia in 2008, occupying two large areas of the nation. 2014 witnessed the Russian annexation of Crimea where in just a week, Russia seized control of Crimea “without firing a shot.” The annexation of Crimea was rapidly followed by a Russian inspired and led subversive war in eastern Ukraine. The common thread among these diverse Russian operations is its use of ambiguity to confound and confuse decision makers in the West.     

Desert insurgency: lessons from the third Tuareg rebellion

This article provides an in-depth examination and analysis of the 2006–2009 Tuareg rebellion in Mali and Niger. It identifies the underlying reasons behind the rebellion, explores contrasting counter-insurgency (COIN) strategies employed by the two governments, and presents some lessons learned. While both COIN approaches ultimately produced similar peace settlements, the article argues that the Malian strategy of reconciliation combined with the selective use of force was far more effective than the Nigerien iron fist approach at limiting the size and scope of the insurgency and producing a more sustainable peace. It concludes by looking at the role of external actors, particularly the United States, and how the failure to internationalize the conflict was actually more beneficial to the local COIN effort, as well as to the longer strategic interests of the United States in the region.
