X波段雷达前门防护技术研究

为了提高X波段雷达的带外抑制能力,在传统方形环孔的基础上,设计了一种新型带通FSS单元。运用谱域法对这种新型单元的传输系数进行了数值计算。计算结果表明:该新型频率选择表面(FSS)的工作带宽为8～12 GHz,该新型单元具有极好的角度稳定性。入射角度φ从0°到90°变化时,工作带宽漂移量不超过100 MHz;入射角度θ从0°到45°变化时,工作带宽漂移量不超过400 MHz。应用于X波段(8～12 GHz)雷达天线上,可提高其带外抗干扰的能力。

考虑腐蚀因素的船体结构寿命预测方法

为建立考虑腐蚀因素的船体结构寿命预测方法,在分析现有常用的船体结构腐蚀损伤时变模型的基础上,根据舰船维修保障实际情况建立了考虑腐蚀防护系统作用时间和维修时间等因素的腐蚀时变模型。根据相关规范选择了船体结构腐蚀寿命标准,并建立了一种计算船体结构腐蚀寿命的方法。该方法建立了船体结构腐蚀寿命与腐蚀防护系统作用时间和修理时间等因素之间的量化关系,可以用于预测均匀腐蚀条件下船体结构寿命,也可以反过来指导腐蚀防护系统设计指标的选择和船体结构维修策略的确定。

Assessing military reform in Indonesia

This article seeks to assess the magnitude of military reform in Indonesia and its impact in establishing greater levels of professionalism within the armed forces. To this end, the authors will offer some reflections on the studies of civil-military relations and military transformation for inculcating a higher degree of military professionalism; analyse to what extent the process of military reform in Indonesia has reshaped the institutional role of the armed forces; and discern three major strategic gaps in Indonesia's military reform, namely the “legal loopholes and regulation vacuum,” the “shortcomings of democratic civilian control,” and the “defence-economic gap.” This article asserts that military professionalism will grow more substantially depending on the ability of civilian elites to exercise effective control over the military and the capacity of the government to transform the military establishment keeping pace with strategic challenges and operational requirements.     

The year of the drone misinformation

This paper challenges the widely held view in the research communities around the world that US drone strikes on the Pakistan's north-western border area with Afghanistan lead to large-scale civilian casualties and are unpopular in that tribal area. As an example of that view the author analyses a recent research report, ‘The Year of the Drone’, produced by the New American Foundation, and argues that sources of the report are questionable and doubtful. The author, who is a native of the border area with Afghanistan and has lived almost all of her lifetime in the area, informs that the drone attacks are popular in the region and the reports about large-scale civilian casualties are baseless. She provides some evidence in support of her argument and cautions the researchers against the uncritical acceptance of the notions, like the drone attacks are unpopular or have killed civilians.
