一种通用型舰载防空硬武器火力优化算法?

针对当前武器优化分配算法缺少通用性,难以兼顾效率和时间的问题,提出了一种通用型舰载防空硬武器火力优化算法。该算法首先提取各舰载武器能够攻击的目标集合,然后对各武器的目标集合逐一进行时间分配,并计算对目标的毁伤概率,最终完成所有武器的分配。计算表明,该算法具有很好的通用性和实时性,可适用于较大规模舰载防空硬武器的火力优化分配问题。

Challenges of institutional coordination in complex defense acquisition programs: the case of the Republic of Korea’s F-X program

Decision-making in defense acquisition programs in the Republic of Korea (ROK) has been problematic, especially in highly advanced complex systems. The highly disputed force modernization program for the ROK Air Force’s fifth-generation fighter, dubbed the Fighter eXperiment, went through extreme turbulence during the type selection phase. The gist of the turbulence became evident through poor institutional coordination within the defense acquisition authorities that eventually forced them to rescind the decision generated from their own yearlong efforts, thus basically shooting themselves on the foot. The paper highlights the background of the program and reviews the institutional elements that influenced the decision-making process, and conclude that the absence of an effective coordination mechanism has made decision-making in complex defense programs even more troublesome.     

Defense policy in Brazil: bridging the gap between ends and means?

This article aims to analyze the Brazilian Defense Policy in terms of its ability to reduce the gap between ends and means. Since 2003, the Brazilian defense policy has evolved along with Brazil’s increased role in the international system. Sustaining this process depends on institutional, economic, and operational conditions that are yet to be fully guaranteed. They require negotiations, reforms, and strategic perspective. By identifying specific challenges emerging from the national security institutional framework, the combat capability building process, the budgetary cycle, as well as from the defense industrial base, we sought to explain their rationale and to offer concrete policy pointers to overcome obstacles. As a general conclusion, the Brazilian defense policy was strengthened by the 2008 National Defense Strategy (END) due to its clearer strategic goals. Bridging the gap between those ends and the proper means is a continuous effort for any given country, but in the case of Brazil it has been addressed with firmer steps since the END, even in the face of harder economic and political conditions.

多功能复杂信号侦察可配置计算模型

复杂信号侦察处理是多功能数字阵列雷达(MFDAR)的重要组成部分,可以服务于MFDAR的雷达与通信信号侦察以及电子战等多种用途,其中信号侦察的实时性与功能的灵活适应性是MFDAR的关键。在详细研究MFDAR信号侦察处理特点基础上,提出了两阶段可配置的信号处理流程,构建了基于混合结构的宽带信号侦察可配置计算模型BSRRCM。BSRRCM对"非确定、非单向"的信号流进行了描述,利用"固化典型流程、设置有限配置点"的思想,BSRRCM将应用分解成可完全重配置的典型处理流程和可局部重配置的功能任务序列,快速映射到合适的计算平台上,在确保信号处理实时性前提下使系统获得了动态的灵活配置能力与可扩展性。
