星载光学遥感成像系统复杂性分析

为研究星载光学遥感成像系统的复杂性,由复杂系统的基本特征与系统研究的基本原则出发,通过对成像全链路流程的分析,确定光学遥感成像系统的复杂性来源及其表现形式。建立星载光学成像的数学模型,以系统重要参数——调制传递函数为基点,通过正过程建模分析和逆过程测量计算相结合的方式,分析了系统复杂性研究的基本原则,即还原论与整体论相结合、定性与定量相结合的过程。由正、逆过程的对比分析,一方面阐述了系统性能与各个环节参数之间的关系,另一方面又由正则化盲反卷积的方式得到图像中真实的调制传递函数。二者相辅相成,既能通过补偿系统复杂性因素影响提升系统性能,又能进一步指导系统优化设计。     

基于0-1分辨矩阵的集群探测盲区判定

针对航空集群协同反隐身探测盲区的识别判定问题,在多种编队构型下的集群协同探测仿真结果的基础上,运用属性的0-1分辨矩阵方法进行识别,对于连通的区域,建立相关模型,求得允许目标通过的最小宽度,将建立的模型应用到模拟作战中,仿真结果验证模型的正确性和合理性。结论表明,航空集群协同横向探测盲区可视为探测区下的保护区;纵向探测盲区则视为连通区域;斜探测盲区的判定,则依据通道倾斜角、通道长度和宽度的比值而定。

The Millenials’ war: dilemmas of network dependency in today’s military

This work is about how the United States military has become dependent on networked technology. As arguably the largest contributor to national security, it has become so dependent that its chief doctrine integrates networked technology into nearly every specialty, with particularly intense focus on Network Centric Warfare. As the military’s old guard is replaced by the highly technical Millenial Generation, there is cause to pause when assuming this techno-acuity brings nothing but advantage and success. Vulnerabilities stemming from such extensive dependence offer opportunities for exploitation that have not gone unnoticed. The first step to moving forward from this point is to fully understand the extent to which the military has become dependent on computer networks. It might be the Millenials’ war today, but it would be quite unwise for the United States military to think about it and fight it in a purely Millenial way.     

US–Latin America’s security: moving through an inflection point?

Recent elections in Latin America, such as those of Mauricio Macri in Argentina, Horacio Cartes in Paraguay, and the impeachment process of Dilma Rousseff in Brazil, point to a new direction in Latin American politics and away from the “hard left;” they also point to a new momentum in the security relationship between the US and Latin American countries. Former US President Obama’s 2016 trip to Cuba and Argentina was a clear demonstration of this new security paradigm and also a clear indication that there is a new momentum brewing in the US towards a rethinking and reshaping of security strategies and mindsets. This article will explore the multidimensional security relationship between the US and Latin American countries in light of recent changes in the US’ posture toward the region.     

The underlying causes of military outsourcing in the USA and UK: bridging the persistent gap between ends,ways and means since the beginning of the Cold War

This article reappraises the two most-studied country cases of military outsourcing: the USA and the UK. It argues that the contemporary wave of military contracting stretches back to the beginning of the cold war and not only to the demobilisation of armies in the 1990s or the neoliberal reforms introduced since the 1980s. It traces the political, technological and ideational developments that laid the groundwork for these reforms and practices since the early cold war and account for its endurance today. Importantly, it argues that a persistent gap between strategic objectives and resources, i.e. the challenge to reconcile ends and means, is an underlying driver of military contracting in both countries. Contemporary contracting is thus most closely tied to military support functions in support of wider foreign and defence political objectives. Security services in either state may not have been outsourced so swiftly, if at all, without decades of experience in outsourcing military logistics functions and the resultant vehicles, processes and familiarities with public-private partnerships. The article thus provides a wider and deeper understanding of the drivers of contractualisation, thereby improving our understanding of both its historical trajectory and the determinants of its present and potential futures.
