舰载近区防卫武器综合运用

水面舰艇近区防卫武器的作战运用研究是舰载武器作战运用研究的新课题。在分析近区防卫目标特征、武器特点、作战方法的基础上,提出近区防卫武器综合运用一般原则,基于作战时域的连续性及效果的叠加性,构建近区防卫武器使用逻辑结构,建立武器运用的对策模型,可为近区防卫武器的科学使用提供理论参考。     

舰载预警机防空预警探测距离需求分析

提出了一种舰载预警机防空预警探测距离需求确定方法。首先对舰载预警机执行防空预警作战进行了描述,为满足拦截机对敌突击飞机进行成功拦截,预警机的预警探测距必须大于一个阈值,即所需最小预警探测距离。其次分析了舰载预警机所需最小防空预警探测距离与敌突击飞机速度、航母防空拦截机响应时间和速度之间的关系,构建了舰载预警机防空所需最小预警探测距离计算模型;最后应用典型案例,计算了多种防空想定下舰载预警机所需最小预警探测距离,仿真分析了敌突击飞机速度和航母防空拦截机速度对舰载预警机防空所需最小预警探测距离的影响。论文的研究结果为舰载预警机装备研制和作战使用提供决策依据。     

Hoping for the Best,preparing for the worst: China's response to US hegemony

In the post-Cold War strategic environment, Beijing could plausibly have opted for Soviet-style geostrategic competition with Washington, but it has not. Chinese leaders have not thus far, and almost certainly will never, amass thousands of nuclear weapons on hair-trigger alert or deploy significant forces to a network of bases spanning the globe. Nevertheless, the below assessment of China's increasing hard and soft power yields the conclusion that a Chinese challenge to US hegemony cannot be ruled out. The United States must prudently maintain military forces appropriate to facing a potential peer competitor. At the same time, however, Washington must engage in a process of creative diplomacy that simultaneously matches China's soft power and engages seriously with Beijing to create areas of consensus and cooperation.     

The origins of the cancellation of Canada's Avro CF-105 arrow fighter program: A failure of strategy

The story of the demise of Canada's remarkable CF-105 Arrow jet-fighter interceptor has been told and retold by numerous Canadian writers. As told by most, it is a tragic tale. Canadian Prime Minister John Diefenbaker, in an act as unforgivable as it was incomprehensible, not only destroyed a highly promising all-Canadian state-of-the-art aircraft but ruined all hopes of Canada ever being an important player in the North American defense industry. This article offers a contrasting interpretation — locating the problems leading to the aircraft's cancellation further back in history, and in particular in serious and determinative failures in strategic thinking and analysis by senior Canadian military officials at the time of the Arrow program's birth in 1953.     

The knapsack problem with a minimum filling constraint

We study a knapsack problem with an additional minimum filling constraint, such that the total weight of selected items cannot be less than a given threshold. The problem has several applications in shipping, e‐commerce, and transportation service procurement. When the threshold equals the knapsack capacity, even finding a feasible solution to the problem is NP‐hard. Therefore, we consider the case when the ratio α of threshold to capacity is less than 1. For this case, we develop an approximation scheme that returns a feasible solution with a total profit not less than (1 ‐ ε) times the total profit of an optimal solution for any ε > 0, and with a running time polynomial in the number of items, 1/ε, and 1/(1‐α). © 2012 Wiley Periodicals, Inc.

The Amritsar Massacre and the minimum force debate

This article re-examines one of the most infamous incidents in British imperial history: the Amritsar Massacre of 1919, and analyses it within the context of the British Army's minimum force philosophy. The massacre has long been regarded as the most catastrophic failure of minimum force in the history of the British Army. This article reconsiders the arguments over the shooting at Amritsar and the role of Brigadier-General Reginald Dyer, and questions the accepted view that the massacre was such a failure of minimum force. It argues that the circumstances surrounding the massacre must be understood before judging the incident and given these factors it is possible to see it within a minimum force framework.     

‘Troops were then forced to fire’: British army crowd control in Palestine,November 1945

In November 1945, British army shooting during street riots and search operations in Palestine resulted in the death of 13 Jews and the injuring of dozens. The most costly in casualties caused by army fire during the whole Jewish insurgency, these incidents have nevertheless not received detailed attention in literature on the British army's counterinsurgency campaign in postwar Palestine. This article outlines British military use of firepower to control civilian crowds and the difficulties involved during these incidents, contributing to the debate on the army's principal of ‘minimum force’. It also highlights the serious problem of legitimizing opening of fire on unarmed protestors, epitomized in the army's fabricated account justifying shooting at a large crowd rushing a military cordon at Givat Hayim.     

机动目标状态估计的最小均方误差界

基于多项式模型的各种自适应滤波算法被广泛应用于机动目标跟踪领域,但尚没有统一的评估标准来衡量这些跟踪算法的优劣。由于存在确定的时变未知输入,机动目标的状态估计实际为有偏估计。基于状态估计均方误差最小的准则,推导了多项式模型滤波的最小均方误差界计算方法,获得了使状态估计均方误差最小的过程噪声方差变化规律。该方法给出了各种基于多项式模型的机动目标跟踪算法的估计均方误差下限,也为机动目标跟踪中最优过程噪声方差的设定提供了依据。仿真结果验证了算法的有效性。
