The fertile ground of Hell’s carnival: Charles T. R. Bohannan and the US Army’s Counter Intelligence Corps’ investigations of war criminals,collaborators, and the Huk,in the Philippines 1945–1947

Insurgencies thrive in regions where government legitimacy is absent. In the post-war Philippines, Captain Charles T. R. Bohannan of the Army’s Counter Intelligence Corps became actively aware of this dynamic. Bohannan is best known for his later work with Edward Lansdale and Ramon Magsaysay in defeating the Huk Rebellion (1950–1954). Here the author examines Bohannan’s early investigative work against Japanese war criminals, wartime Filipino collaborators, and the rising threat of communist subversion most associated with the Huk. All of these experiences fed into what would be the successful campaign against the Huk, chronicled in his seminal work, Counter Guerrilla Operations: The Philippines Experience, and offers lessons on the investigative (as opposed to tactical or psychological) nature of effective counter-insurgency work, as it relates to both legitimacy in governance and the rise of insurgencies.     

从大国博弈视角解读与应对第三次抵消战略

在常规军力优势相对衰落、经费预算日益缩紧的背景下,美军为维持其军事霸权,提出了旨在实现兵力全球自由投送的第三次抵消战略(Third Offset Strategy)。通过梳理抵消战略的现实背景、历史沿革和战略目的,我们发现如果把第三次抵消战略简单视作美军的军事技术发展战略甚至军事战略,就会陷入片面而幼稚的认识误区。除了防范潜在的技术诱骗和技术突袭,更应该从大国博弈的战略视角出发,全面审视和应对第三次抵消战略对我国的挑战。美军实现国家利益的需求导向、自我变革的决心勇气和创新能力、科技兴军的先进理念和以军为主的军民融合成功经验值得借鉴。要以我为主参与制定未来战争的"游戏规则",做到"你打你的,我打我的";要深入研究美军作战体系和美国国家战略的薄弱环节,有针对性地"攻其所必救",从而化解重大安全挑战,争得新的战略机遇期。     

助飞鱼雷机动区域射击法攻潜能力研究

以飞航式助飞鱼雷为例,在分析助飞鱼雷攻潜过程的基础上,针对机动目标提出了在无指令修正情况下助飞鱼雷的机动区域射击法,并运用解析法对射击诸元进行解算。在建立助飞鱼雷作战能力仿真模型时,围绕捕获概率、鱼雷仿真和目标仿真等方面进行模型的构建,并采用蒙特卡罗方法进行仿真计算,分析采用机动区域射击方法时影响助飞鱼雷攻潜能力的主要因素及其规律,为更好发挥武器对机动目标的打击能力提供理论参考。     

The People’s Liberation Army and China’s Smart Power Quandary in Southeast Asia

Abstract

China has a strong interest in pursuing a smart power strategy towards Southeast Asia and has worked laboriously to engage with regional countries economically, socially, and politically. But China has been only partially successful in achieving its goals in the region. This paper argues that China’s security policy towards Southeast Asia significantly contradicts many other objectives that Beijing wishes to accomplish. Given the deep-seated, narrowly-defined national interests of the Chinese military in the South China Sea disputes, it is likely that the People’s Liberation Army (PLA) will continue to pose the main obstacle to the effective implementation of a Chinese smart strategy in Southeast Asia.     

一种自适应Harris角点检测算法

针对传统算法检测效果不理想的问题,提出了一种基于自适应非最大抑制策略的Harris角点检测算法;通过设置抑制半径与角点响应函数的局部最大值关联,减小抑制半径获取角点。算法有效解决了阈值选取和"聚簇"的问题。实验表明,该算法检测出的角点均匀分布,能很好地适应特征匹配等实际应用。

改进Costas环的GPS载波跟踪环路

针对高动态环境下载波信号会产生较大多普勒频移而导致跟踪环路失锁的问题,对其基带信号进行双向限幅以改进Costas环的鉴相特性。同时,采用叉积型鉴频器,通过频率牵引使捕获后的频差达到跟踪模块的工作范围,并根据对锁相环和锁频环的特性分析及其各自的优缺点,选择锁频环辅助锁相环的复合结构。仿真试验结果表明,在高动态环境下(运动速度1 200 m/s)该跟踪环可以快速跟踪卫星信号,即时误差趋近于0,且当加速度达到40 g以上时,经过该复合环跟踪后的多普勒频移比传统锁相环减小了50%以上。     

论边防警察的心理应激与应对

心理应激是一种特殊的情绪状态,在这种情绪状态下个体会有很多特殊的反应和举动。边防警察由于其工作的特殊性,难免会产生心理应激。边防警察的心理应激源包括工作方面、环境方面、生活方面。分析了边防警察心理应激的类型及表现,主要从培养品质和意志,学会放松,取得社会、家人、亲友的支持和理解,加强心理训练等方面论述了应对边防警察心理应激的措施。
