BRAZIL AND MEXICO IN THE NONPROLIFERATION REGIME

Latin American countries have historically followed different paths and logics toward the nonproliferation regime. Some states have unconditionally advocated for global and nonproliferation efforts, while others have vehemently opposed such measures or remained ambivalent toward the regime itself. By historically comparing two of Latin America's most influential countries—Brazil and Mexico—this study identifies the underlying domestic conditions and external influences that explain their differences in behavior and policy toward the nonproliferation regime. Because little is known about the reasons why different Latin American countries adopt these different approaches, the purpose of this article is to resolve this problem, primarily by focusing on the ways in which evolving civil-military relations and US influence have shaped nonproliferation policy preferences in Latin America. It concludes with a discussion of how these historical cases might shed light on current nonproliferation policies in Latin America.     

探测平台目指精度对反舰导弹捕捉效能影响分析*

随着反舰导弹射程的不断增加,反舰导弹远程攻击需要使用远程探测平台提供目标指示。针对反舰导弹与远程探测平台的协同使用问题,提出反舰导弹采用"现在点"射击方式时,探测平台的目指精度与反舰导弹捕捉效能的相关分析模型。通过对模型的仿真计算,得出在不同使用条件下,影响导弹捕捉效能的目指精度。研究表明,导弹射击所需要的目指精度是一个随多个因素变化的量,应根据导弹射击的具体情况,确定相应的目指精度。     

地心甚高轨道星座构形协同捕获控制策略

针对地心甚高轨道星座构形协同捕获控制问题,基于虚拟编队方法设计了协同捕获控制策略,采用三脉冲燃耗最优轨迹规划算法对构形捕获轨迹进行协同规划;并且结合自适应全程积分滑模控制器对卫星各自转移轨迹进行跟踪控制。以10万km轨道高度的三星星座构形捕获为例进行仿真验证,仿真结果表明:该策略可以有效应用于地心甚高轨道星座构形捕获控制,能够在燃耗较少的情况下使星座中卫星同时到达各自的标称位置,同时具有较高的精度。

The subversion of the Bulgarian defence system – the Russian way

Russia has long been pursuing an intended and calculated policy of keeping enough influence in Bulgaria in order to have control over national decisions. Together with the economic, energy, political and information tools used by Russia in its hybrid war against Bulgaria and in its bid to achieve an enduring “state capture,” defence is also a distinct target of Russian subversion now. A list of noticeable subversive actions with tangible effects can be summarised, ranging from fuelling division and manipulating public opinion, preventing the strengthening of the NATO position in the Black Sea, sabotaging defence reform to various options of subverting the modernisation of the Bulgarian Armed Forces and seeking new ways to keep legacy Soviet military equipment in operation as long as possible. This issue must be urgently addressed both nationally and in NATO.
