主动声纳浮标可以实现对潜艇的精确定位,但易被潜艇感知采取机动规避措施,为了有效减少被主动声纳浮标发现的概率和暴露时间,提出了潜艇自主规避的决策算法,并针对一型主动声纳浮标阵探测进行仿真,分析探测概率变化规律,由此验证算法的有效性。  相似文献

由于被动声纳浮标隐蔽持续探测,潜艇可能由于机动进入浮标探测范围,从而增加了被探测概率。首先,在分析已有模型局限性的基础上,从潜艇运动对浮标搜索影响的原理出发,建立单枚浮标新增搜索区域模型,分析了单枚浮标搜索概率的影响因素,然后建模分析了潜艇运动对浮标拦截线搜索概率的影响因素,得出了影响作用仅对浮标作用距离、间距和航向敏感的结论,并对作战使用方法提出相关建议。  相似文献

针对潜艇磁性防护,基于磁偶极子阵列模型,建立了潜艇磁性目标高精度磁场计算模型。提出了利用奇异值分解的方法对模型进行求解,利用该求解算法进行了模型计算与实测数据比对,结果表明,该计算方法能够有效适用于计算高精度潜艇磁场。基于奇异分解的方法计算了潜艇高空磁场,计算结果可供潜艇防护磁性探测参考。  相似文献

In January 1950 President Harry S. Truman announced that the United States would proceed with further work to determine the feasibility of a ‘Super’, or hydrogen, bomb. The events leading up to that decision – counter-pressures and advocacy from a number of quarters, including the divided Atomic Energy Commission (AEC), the nuclear scientists, Congress and the Pentagon – is well known. Less attention has been given to how the story of the Super came to be told in official and popular publications. Admiral Lewis L. Strauss, rogue member of the AEC, later presidential adviser on atomic affairs and AEC chairman, was one of the most vigorous advocates of developing thermonuclear weapons. He was also a highly skilled player of bureaucratic politics. This article draws upon the Strauss archives to examine how he used his position and his contacts to shape the history of the H-bomb to his own political advantage.  相似文献

The People's Republic of China (PRC), no longer content with its longstanding ‘minimalist’ nuclear posture and strategy, is enhancing the striking power and survivability of its theater and strategic missile forces and rethinking its nuclear doctrine in ways that may pose serious challenges for the United States. Although the modernization of Chinese nuclear and missile forces may ultimately result in greater strategic deterrence stability, this change will not come about immediately or automatically. Indeed, it is entirely possible that China's growing missile capabilities could decrease crisis stability under certain circumstances, especially in the event of a US–China conflict over Taiwan.  相似文献

The second session of the Preparatory Committee for the 2015 Review Conference (RevCon) of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) highlighted two issues in particular—progress toward a Middle East Weapons of Mass Destruction–Free Zone and the Joint Statement on the humanitarian impact of nuclear weapons—that may not only greatly affect the health and vitality of the NPT and the 2015 RevCon, but possibly also have implications for the international nonproliferation regime as a whole. Dr. William Potter, director of the James Martin Center for Nonproliferation Studies, interviewed Ambassador Cornel Feruta, chairman of the 2013 PrepCom, to discuss these and other issues related to the meeting and the future of the treaty and its review process.  相似文献

The number of bilateral nuclear cooperation agreements surged during the “nuclear renaissance” of the past decade. This proliferation is only partially explained by the prevailing approaches that focus on strategic imperatives. To supplement these explanations, this study draws on neoliberal models of economic competition to posit that bilateral agreement negotiations also exhibit conditions of “uncoordinated interdependence” and maneuvering to gain market share. Case evidence suggests the contours of supplier state bids for civilian assistance are determined at least as much by considerations about economic competition as they are by positive strategic goals. In addition, this study identifies several cases of cooperation where there appears to be little or no strategic motive for export agreements. The study concludes that patterns of economic competition and the influence of peers in defined competitive spaces alter material payoffs and impact policies. It also identifies a surprising role for principled restraint in dampening strategic and economic competition in some dyads.  相似文献

Regrettably, moral arguments are largely absent from the current debate on nuclear disarmament. Indeed, complementing politico-strategic thinking with ethical categories could significantly strengthen the abolitionist call. To fill the gap, this article analyzes the evolution of the nuclear ethics of the Roman Catholic Church and especially its position on nuclear deterrence. If this strategy was granted interim and strictly conditioned moral acceptance during the Cold War, nuclear deterrence is today increasingly considered ineffective, an obstacle to genuine disarmament, and hence morally unjustifiable. In the new security context, the conditions for the Catholic Church's “interim nuclear ethics” have altered, and nuclear disarmament has become a feasible option and an alternative strategy to deterrence.  相似文献
