Special Section: Nuclear Stability In South Asia

The question of nuclear stability in South Asia is a subject of both academic and policy significance. It is the only region in the world that has three, contiguous nuclear-armed states: India, the People's Republic of China, and Pakistan. It is also freighted with unresolved border disputes. To compound matters, all three states are now modernizing their nuclear forces and have expressed scant interest in any form of regional arms control. These issues and developments constitute the basis of this special section, which explores the problems and prospects of nuclear crisis stability in the region.     

基于ExtendSim的小高炮武器系统抗击超音速巡航导弹仿真分析

目前超音速巡航导弹对要地防空的安全威胁越来越严峻,研究高炮部队在各种配置情况下抗击超音速巡航导弹的作战效能日益受到重视。首先对超音速巡航导弹来袭弹道和高炮抗击过程进行分析,在此基础上设计了高炮反导作战仿真流程,随后基于流程构建ExtendSim仿真模型评估高炮部队在各种配置情况下的作战效能,最后对仿真结果进行分析比较研究,所得结论为高炮部队抗击超音速巡航导弹作战配置提供了基本参考和依据。     

Strategic “defensivism” and post-reset blues: US–Russian nuclear arms reductions,missile defenses and minimum deterrence

US nuclear deterrence and arms control policy may be moving, by design and by inadvertence, toward a posture of strategic “defensivism”. Strategic “defensivism” emphasizes the overlapping and reinforcing impact of: (1) reductions in US, Russian and possibly other strategic nuclear forces, possibly down to the level of “minimum deterrence,” (2) deployment of improved strategic and/or theater antimissile defenses for the US, NATO allies and other partners; and (3) additional reliance on conventional military forces for some missions hitherto preferentially assigned to nuclear weapons. This article deals with the first two of these aspects only: the interaction between missile defenses and offensive force reductions in US–Russian strategy and policy. The findings are that stable deterrence as between the USA and Russia is possible at lower than New Strategic Arms Reduction Treaty levels, but reductions below 1000 deployed long-range weapons for each state, toward a true minimum deterrent posture, will require multilateral as opposed to bilateral coordination of arms limitations. Missile defenses might provide some denial capability against light attacks by states with small arsenals, but they still fall short of meaningful damage limitation as between powers capable of massive nuclear strikes.     

美国舰载标准系列导弹对海军防空导弹发展的影响

美国海军现役的标准导弹是一个庞大的系列,主要型号从标准1一直到标准6,每个主要型号又在不同的时期发展出多种改进型。它不仅是美国海军当前的主力舰空导弹武器装备,还出口到多个国家和地区,是世界上装备量最大、应用最为广泛的舰空导弹系统。本文主要结合标准系列导弹的发展历程,分析了标准系列导弹对世界海军防空导弹装备发展的深远影响。     

超声速导弹的光滑二阶滑模控制器设计

建立了带有气动系数不确定量和外界干扰的超声速导弹的运动模型。采用输出重定义技术克服了导弹过载输出的非最小相位特性,利用容易测量的过载和角速度相组合重新定义了新输出量。为了削弱滑模控制的颤振影响,同时又保持滑模控制的强鲁棒性,采用光滑二阶滑模控制方法设计了导弹过载控制系统中的控制器。设计了二阶滑模观测器对汇总不确定量进行有效估计。为了检验所设计的观测器和控制器的控制效果,仿真分析中对比了光滑二阶滑模控制器和传统滑模控制器的仿真结果。仿真结果表明：光滑二阶滑模控制器能够有效地削弱颤振影响,使导弹过载输出快速准确地跟踪上过载指令信号。     

弹道导弹关机点状态估计的指数加权递归最小二乘方法

在双星预警条件下,将指数加权递归最小二乘算法应用于目标关机点状态估计问题中。通过引入加权因子对目标助推段运动的局部拟线性特性进行描述,从而在一定程度上克服了一般的线性多项式模型难以准确刻画整个助推段运动的难题。通过对助推段目标动力学特性的分析,考察了目标在垂直射面方向上的运动特性。在此基础上,提出了一种更为准确的助推段运动模型。仿真算例表明,所提出的关机点状态估计方法相对于传统的方法具有一定的优越性。
