随着全球导航卫星系统的广泛应用,其安全性问题也逐渐成为人们关注的焦点。为了对目前最具隐蔽性的诱导式欺骗技术进行检测,提出一种对两路导航信号同时进行处理的combo-signal模型,并提出基于这种信号处理模型来对诱导式欺骗信号进行检测的方法;分析了该方法的检测门限;采用北斗的B1I 和B1C信号在实现了combo-signal处理模型的软件接收机上对该检测方法进行了验证,实验结果证明该方法可以有效地对诱导式欺骗进行检测,统计得到的检测概率跟前面的分析结果一致。  相似文献

What organisational attributes enhance a military’s ability to effectively adapt on the battlefield? Upon the outbreak of war in July 2014 between Israel and the Palestinian militant group Hamas, the Israel Defense Forces (IDF) encountered an expansive network of tunnels from which Hamas was launching large-scale assaults into Israel. This article illustrates that the IDF’s ability to successfully adapt ‘under fire’ to this battlefield surprise was facilitated by several important attributes related to its organisational learning capacity: a dynamic, action-oriented organisational culture, a flexible leadership and command style, specialised commando units which acted as ‘incubators’ for learning and innovation, and a formal system to institutionalise and disseminate lessons learned.  相似文献

The post-Cold War era has witnessed the rapid expansion of organisational learning initiatives within NATO militaries, especially formal “lessons-learned” processes. The effectiveness of national lessons-learned processes in recalibrating military activity to the demands of ongoing operations has been highly-differentiated. However, the academic literature on military change and practitioner guidance has been slow to investigate the key features of best-practice in military learning. This article breaks new ground by drawing upon the literature on dynamic organisational capabilities to explore the fundamental organisational processes and activities which are necessary to implement successful lessons-learned. It examines, in particular, the organisational features which facilitate “knowledge transformation”: the effective combination of new knowledge gained from intra- and inter-organisational learning with existing organisational knowledge. The article concludes by highlighting several potential future empirical and theoretical research agendas in military learning and the importance of engagement between lessons-learned practitioners and organisational learning scholars.  相似文献

In the mid-2000s, the United States Army was embroiled in counterinsurgency missions in Iraq and Afghanistan that required deeper understanding of local social systems. The Army turned to systems thinking and design thinking to model and understand the world, define problems, and develop approaches to strategic and operational challenges. However, the Army’s approach as expressed in publications and doctrine encourages the development of complicated, unsupported, and unfalsifiable hypotheses. The risk is that the Army will act on incorrect assumptions and develop plans that are fragile.  相似文献

Whistleblowing has gained increasing media attention over the past 40 years, as incidents of abuse and wrongdoing associated with businesses, religious institutions, the media and politics have come to light. In this article, we investigate the consequences of a military whistleblower’s actions for both himself and the military institution that he was a part of. The case concerns former army officer Dr. Tom Clonan and his findings concerning the bullying and sexual harassment of female personnel in the Irish Defence Forces at the turn of the century. As these revelations came to light over 17 years ago we are able to examine their consequences for the military since that time.  相似文献

The rise of private military and security companies (PMSCs) challenges our notion of military professionals. PMSCs bring new claims to professional status and legitimacy outside military institutions and represent an increasing diffusion of - and competition over - military and security expertise. In light of this development, understanding the formation of professional identities in military and private security organisations is as an important undertaking. This paper contributes to this endeavour by analysing professional self-images in the Swedish Armed Forces and how these relate to PMSCs. The study is based on data collected from official documents, semi-structured interviews and a small-scale survey among senior military officers. Focusing on military understandings of PMSCs and contractors, the analysis provides much-needed insight into relational aspects of professional identity formation outside the US context. Furthermore, it points to discrepancies in organisational and group levels in understandings of commercial security actors, and paves the way for future research.  相似文献

Once dismissed by many outside observers, the Chinese People’s Liberation Army Air Force (PLAAF) has undergone an impressive transformation over the past two decades, emerging as one of the world’s premier air forces. As it continues to modernize, it is focused on becoming a ‘strategic air force.’ PLAAF strategists suggest this means it should play a decisive role in protecting Chinese national interests, field modern capabilities commensurate with China’s standing as a major power, and enjoy the institutional status befitting its role as a ‘strategic service,’ an important consideration given the historical dominance of the ground force in China’s military.  相似文献
