地空导弹在火力对抗条件下的生存能力 总被引:1,自引:0,他引:1
在火力对抗条件下地空导弹提高生存能力的主要办法是避免被空中目标过早发现,尽早对空中目标进行火力拦截,提高在对抗过程中的拦截次数,增大每次对空中目标进行大力拦截的杀伤概率,直接拦截空袭武器和提高自身抗毁伤的能力。 相似文献

角度闪烁干扰对地空导弹火力拦截能力的影响,是电子对抗部队迫切需要解决却又缺乏系统研究的难题。为解决这一难点问题,首先在研究杀伤区纵深和掩护扇区受干扰变化的基础上,分析了双机闪烁干扰对地空导弹射击目标脱靶量及射击次数的影响,然后建立了角度闪烁干扰条件下地空导弹对目标的合成杀伤概率计算模型,最后通过算例验证模型的有效性,得出了具有实用价值的结论,可为空袭作战中作战效能评估提供参考。 相似文献

基于地空导弹(红方)对空中编队(蓝方)的拦截过程中的薄弱环节以及蓝方对红方实施的电子战措施的分析,对蓝方实施的电子战对红方拦截行动的影响进行了定量评估,得出蓝方突防概率与电子战综合作战效能之间的函数关系。仿真结果表明,对地空导弹拦截的每一环节都可以有效地实施电子战,削弱地空导弹的拦截能力。 相似文献

高层体系结构HLA建立一个通用的仿真框架,以解决不同仿真器、模型之间的互操作及仿真组件的可重用性问题.针对当前空防对抗的主要特点,在地空导弹拦截的数学模型的基础上,利用HLA技术框架,详细地叙述了地空导弹拦截仿真系统的开发过程.仿真试验表明该系统能有效评估地空导弹火力单元对来袭目标的有效抗击效率和火力范围,为地空导弹火力单元的部署和作战效能的改进提供辅助决策手段. 相似文献

苏联已成功地研制出了一种新型的战术地空导弹。其有效射程仅次于大型战略地空导弹。它较小的体积使它比西方具有相同射程的导弹系统更易运输;其独特的制导系统使它更具有抗多种形式干抗的能力;其可靠性和有效性已被证实,而且已开始输出到它的盟国;其摧毁战术导弹的能力也被证实,而且预估稍加改进到1995年将使其射程增加一倍,扩展了攻击区,即使目标消失在雷达水平线之下,也能够拦截目标。 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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。 相似文献

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. 相似文献

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. 相似文献
