Intelligence reform and the transformation of the state: the end of a French exception

ABSTRACT

This article argues that the intelligence sector is a privileged vantage point to observe and analyse a transformation of the State in France, as this transformation deeply affects the heart of the executive power and the French intelligence and security apparatus. Traditionally, intelligence was not conceived in France as a functional tool in the hands of the decision-maker but was rather defined as a ‘regalian power’. Intelligence activities were derived from a very specific conception of the State, and especially the particular notion of ‘reason of State’ (raison d’État). The current intelligence reform prompts speculation as to whether it represents more than a ‘simple’ functional reorganisation or in fact could signify that intelligence is now recognised as a tool in the hands of a ‘État de droit’ (‘liberal state’). The idea of a French ‘exceptionalism’ is addressed through a theoretical approach of the way France redefines intelligence and surveillance in relation with a major evolution of the notion of ‘reason of State’ itself. Then the article illustrates the assumption of a ‘lost tradition’ of reason of State through an analysis of the current reform of the intelligence sector in France. This reform is based on processes of rationalisation, centralization, modernisation and normalisation of both intelligence activities and intelligence services in France. As a conclusion, the article addresses the reactions to the January and November 2015 terrorist attacks in Paris, and asks whether resilience towards terrorism requires to accelerate the pace of the transformation of the French intelligence sector.     

防空火力单元射击有利度计算方法

根据防空作战的实际,分析了传统算法在计算防空火力单元射击有利度过程中存在的局限性,引入了防空火力单元可射击系数、电磁环境修正系数这两个参数,并结合高炮、地空导弹武器系统的差异,对防空火力单元可射击系数、电磁环境修正系数这两个参数的具体计算方法进行了介绍。在此基础之上,对传统算法进行了改进,提高了防空火力单元射击有利度计算算法的合理性和科学性。     

区域反导指控系统一体化研究

不断发展的TBM突防技术呈现了许多新特点,对防空反导系统的指挥控制能力提出了更高的要求.必须从对TBM的感知、识别、预报、威胁判断、目标分配、火力拦截和效能评估等诸多控制环节进行一体化设计,而信息网络技术的发展又为联合一体化指控这一必然选择提供了可能,通过高速数据链将各个作战平台连接成为无缝战场态势,从而形成一体化的扁平作战体系.通过研究国内外指控系统的发展现状,给出了我军的一体化指控系统的发展建议.     

巡航导弹综合防御系统仿真研究

巡航导弹超低空突防效果好、命中精度高、价格低廉,这些优越的性能使其在近几次局部战争中大显身手,越来越受到世界各国的高度重视,也促使各国纷纷研究巡航导弹及其防御措施.国内对巡航导弹的防御研究多从电子对抗与火力打击两方面分别入手,缺乏对巡航导弹的综合防御系统及其仿真的研究.为了更好地研究巡航导弹的综合防御问题,在分析巡航导弹防御方法的基础上,提出构建对巡航导弹进行软硬对抗的综合防御系统,并建立了基于DIS的综合防御系统仿真框架,介绍了系统的体系结构和模型体系,对进一步深化巡航导弹防御研究具有重要的意义.

A usable past: a contemporary approach to history for the Western profession of arms

The most effective way for the Western profession of arms to use history is to disavow the purism and narrow specialisation of today’s academia in favour of developing a contemporary approach to the subject. The latter aims to foster a range of applied diagnostic skills that transcend the temporal dimensions of past, present, and future. A contemporary approach to history for military professionals emphasises the use of inter-disciplinary war studies to enhance policy relevance. In any defense and security organisation, history must be usable in the sense of providing cognitive and interpretative skills for probing relationships between possibility and actuality, between experience and expectation, and between singularity and repetition. Using history to examine such dialectical interconnections is particularly valuable when military establishments confront their essential task of analyzing emerging trends in the future of war.

Validation of a strategy for harbor defense based on the use of a min‐max algorithm receding horizon control law

We present a validation of a centralized feedback control law for robotic or partially robotic water craft whose task is to defend a harbor from an intruding fleet of water craft. Our work was motivated by the need to provide harbor defenses against hostile, possibly suicidal intruders, preferably using unmanned craft to limit potential casualties. Our feedback control law is a sample‐data receding horizon control law, which requires the solution of a complex max‐min problem at the start of each sample time. In developing this control law, we had to deal with three challenges. The first was to develop a max‐min problem that captures realistically the nature of the defense‐intrusion game. The second was to ensure the solution of this max‐min problem can be accomplished in a small fraction of the sample time that would be needed to control a possibly fast moving craft. The third, to which this article is dedicated, was to validate the effectiveness of our control law first through computer simulations pitting a computer against a computer or a computer against a human, then through the use of model hovercraft in a laboratory, and finally on the Chesapeake Bay, using Yard Patrol boats. © 2016 Wiley Periodicals, Inc.
