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. 相似文献

An interactive economic model of military spending is proposed. It is quantified on the basis of cross section data for East Asia. Projections of military spending to the end of the decade suggest that the growth of military spending in the region will decline slightly in the current decade. East Asian military spending can, however, be greatly influenced by the path of Chinese and US military efforts. An expansion of military spending by China could cause neighboring countries to greatly increase their military expenditures. 相似文献

This commentary traces the increasing importance of early warning in United Nations (UN) peacekeeping, an emphasis that has emerged in connection with the evolution of protection of civilians mandates in UN peacekeeping missions. It examines the current and emerging practice of early warning in UN peacekeeping as well as the challenges faced, drawing on case studies from the UN missions in South Sudan and the Democratic Republic of the Congo. The authors also propose a set of basic principles upon which early warning in UN peacekeeping operations might be approached in the future. 相似文献

将LFMCW雷达运用于主动防护系统时,由于受到发射信号泄露以及地杂波、噪声等因素的影响,往往难以满足低虚警概率的要求。工程上可以利用MTD技术提高信噪比抑制虚假目标。但对于快速来袭的导弹目标,由于在连续的检测周期内目标往往并非出现在同一个距离分辨单元内,直接采用MTD算法进行信号处理并不能得到理想的检测效果。针对这一问题,首先分析了目标在相邻检测周期跨越距离单元造成的回波相位变化及其对信号积累的影响;其后提出在已知目标速度和未知目标速度的情况下分别进行MTD相位补偿的方法,并通过仿真验证了该方法的有效性。 相似文献
