舰炮火控雷达实测误差时序特性分析建模

针对舰炮火控雷达高精度实时仿真建模的问题,运用高斯分布和正态平稳过程的两种误差序列生成方法,建立火控雷达简化仿真模型。通过对某火控雷达实测数据误差的统计及时序相关性分析,完成误差序列仿真生成与验证,给出了实现舰炮火控雷达探测误差仿真的优选方法。实践证明,正态平稳模型的误差生成方法可以有效满足新型舰炮仿真试验火控雷达建模要求。     

利用时间窗权重进行航迹关联

提出一种利用传感器测量数据的时间窗权重进行航迹关联的方法,将目标运动状态的多维向量(如距离、方位角、俯仰角等)分解为多个一维状态标量;根据每个状态标量与时间的关系,提取两条航迹的共同测量时间区间,将其划分为若干个时间窗,计算对应时间窗内的权重;根据时间窗权重差计算每一个状态标量的航迹相似度;应用DS理论或Bayes理论进行航迹关联决策。     

Globalisation in the defence industry: An exploration of the paradigm for us and European defence firms and the implications for being global players

This paper explores some of the key issues associated with the restructuring of the defence industry. A comparison is made between the US and the European Defence Industrial Bases in terms of the drivers for change and the paradigms within which change has taken place. Having shown that some very important differences exist, the paper then explores the approaches that have been adopted for industry consolidation and references them to the academic literature on mergers and acquisitions (M&As) and strategic alliances (SAs). Given that most of the key defence players recognise the need to be global players, the paper presents an argument that the European firms’ experience of operating with a wide range of forms of corporate alliance will serve them in good stead for operating on a global defence scale. US firms, in contrast, have focused largely on M&A activity.     

Strategic Defense and Attack for Series and Parallel Reliability Systems: Reply to Rejoinder

Kovenock and Roberson's (2012a, b) replication of Hausken’s (2008a) equations and parameter restrictions do not enhance our insight into the defense and attack of reliability systems. This reply intends to fill the remaining understanding gaps.     

Police Corruption: Towards a Working Definition

According to the International Committee of the Red Cross (ICRC) publication Interpretive Guidance on the Notion of Direct Participation in Hostilities under International Humanitarian Law, all civilians (including child soldiers) lose their immunity from direct targeting ‘for so long as’ their actions amount to direct participation in hostilities. All civilians can, however, access the revolving door of protection and return to their civilian activities – complete with full immunity from direct targeting – provided the nature of their direct participation was spontaneous and disorganised. Once it can be ascertained that their participation in hostilities amounts to continuous combative functions, they relinquish their access to the revolving door of protection, and can be targeted at all times until they abandon their formal or functional membership of the belligerent group. This piece analyses how the revolving door phenomenon and the notion of continuous combative functions apply in instances where civilian child soldiers are directly participating in hostilities.     

Through the Looking Glass: The Soviet Military-Technical Revolution and the American Revolution in Military Affairs

The roots of the information technology Revolution in Military Affairs (RMA) can be traced to the mid-1970s, when the West capitalized on scientific-technological developments to neutralize the threat posed by Soviet second echelons. However, the cultivation of the technological seeds of the American RMA preceded the maturation of the conceptual ones. Although it was the US that was laying the technological groundwork for the RMA, Soviet, rather than the American military theorists, were the first to argue that the new range of technological innovations constituted a fundamental discontinuity in the nature of war, which they dubbed the ‘Military-Technical Revolution’ (MTR). About a decade later, this fundamental Soviet approach to the transformations in military affairs was analyzed, adapted and adopted by the US, and designated the RMA. This article deals with the intellectual history of the Soviet MTR and the American RMA.

An Imperfect Jewel: Military Theory and the Military Profession

This article explores a perennial theme in the literature of strategic studies: the relationship between military theory and the military profession. It begins with a conceptual analysis of this relationship. It then investigates what military theorists themselves have had to say about the utility of their craft. It concludes by assessing the actual influence of military theory on selected individuals and institutions. The individuals are George S. Patton, Jr., and Ulysses S. Grant. The institutions are the United States Army and the United States Air Force in the late twentieth century. The fundamental finding is suggested in the title: military theory can indeed be quite useful in the maturation of military commanders and in the development of martial institutions, but it is not always necessary and by no means perfect. It should thus be studied assiduously but used with caution.
