基于Bayes统计理论的射表编拟方法

全面系统阐述了Bayes统计理论下的射表编拟方法,具体研究了验前信息的处理、符合计算、编拟计算及试验用弹量的确定等几个关键难点问题,同时导出了确定先验分布中未知参数的计算公式、射表基本诸元的后验估计公式、射表试验用弹量的计算公式。通过两个实例对其具体使用方法给予了详细说明并对其结果进行了分析,指出应用该方法可以在相同精度要求下节省用弹量或在相同用弹量下提高射表精度,具有很好的经济适用价值。     

杂波对空中平台侦察的影响分析

为从功率角度说明杂波对空中侦察设备的影响,提出一种新的杂波功率计算方法,该方法将杂波功率计算从单散射块的简单模型扩展到全向散射空间的精确模型。首先,选取合适的杂波后向散射系数模型;其次,构建空中平台与机载雷达的几何模型,详细地推导了等距离环数学表达式,在考虑距离模糊情况下推导了杂波功率数学表达式;最后,仿真结果表明:该方法比文献杂波功率计算方法更加准确,从功率角度说明了杂波对侦察的影响,为后面研究杂波抑制奠定了基础。     

基于组合赋权法的联合作战协同效能评估指标

针对联合作战协同效能评估指标体系不够科学和权重计算方法比较单一的问题,立足联合作战协同的本质特性和作战协同效能评估尺度,通过维度映射构建了包括整体性、精确性、时效性、灵活性和稳定性等5个一级指标、作战行动有序性、力量优势互补程度等10个二级指标的联合作战协同效能评估指标体系。通过构建离差最小组合赋权模型给出了主客观赋权合成的方法,并结合指标体系权重计算验证了方法可行性。

Competitive Statehood in Libya: Governing Differently a Specific Setting or Deconstructing its Weak Sovereign State with a Fateful Drift Toward Chaos?

Abstract

Libya in 2011 witnessed a real process of political change, though different from all the policy-oriented jargon equating transition with a teleological transition to democracy. Due to the resilience of the Qadhafi regime in power and with the essential role of NATO intervention, the process was eased out by a eight-month civil war. Governance in post-Qadhafi Libya was not done through the rebuilding of centralized authorities. But it took the specific form of the emergence of multiple non-state actors embedded in local dynamics and then connected with weakened central authorities that had access to the huge Libyan resources. That raised complex questions about the quality of this mode of governance, especially at a time of pressing problems for Libya and its neighbors, whether direct ones (Tunisia, Egypt, Mali) or farther countries across the Mediterranean sea: terrorism with the expansion of Da’esh into the country and flows of refugees crossing Libya’s uncontrolled borders and flowing into Italy and then Europe by thousands.

Multilateral defense cooperation in the Indo-Asia-Pacific region: Tentative steps toward a regional NATO?

Some U.S. military leaders have asserted that the United States, Japan, Australia, and India and the Republic of Korea are developing multilateral defense cooperation to deter aggression and uphold norms much like North Atlantic Treaty Organization (NATO) has in Europe. Frequent military exercises and China’s threats to freedom of navigation (FoN) and North Korea’s nuclear missiles comprise the motive force for such cooperation. However, cooperation thus far has been trilateral and minimal, given divergent national interests and dispersed geopolitical locations. Cooperation among Japan, Republic of Korea (ROK), and the United States is increasing given the threat, but ROK’s public opinion is divided about Japan. Australia, Japan, and India have increased cooperation with the United States but are reluctant to conduct FoN operations with the United States to challenge China’s expansionism in the South China Sea. If China becomes more aggressive and blocks FoN or seizes territory, development toward an Asian NATO is possible.
