Controlled warfare: how directed-energy weapons will enable the US Military to fight effectively in an urban environment while minimizing collateral damage

US military operations are increasingly conducted within urban environments and with these operations come the risk of increasing the number of civilian casualties and infrastructure damage. The use of non-lethal weaponry, such as directed-energy weapons, is one method for minimizing collateral damage. This method enables US military forces to effectively fight within urban environments through force escalation capabilities. Using a series of historical examples and future scenarios for urban warfare, this article highlights deficiencies affecting military capabilities in military urban operations, addresses the consequences of collateral damage, assesses the effectiveness of directed-energy weapons in military urban operations and encourages further funding, research and integration of non-lethal weaponry, such as directed-energy weapons, within the US military.     

Winning hearts and minds: legitimacy in the Namibian war for independence

Efforts at winning hearts and minds (WHAM) impact on and are affected by perceptions of legitimacy. In the Namibian war for independence (1966–1989) efforts of the South African counterinsurgent forces at winning hearts and minds focused mainly on persuading the population to cooperate in exchange for material benefits and services. The article demonstrates that this successfully contributed to a dimension of legitimacy that is conceptualized as pragmatic legitimacy. However, other dimensions of legitimacy are identified in which the South Africans were lacking, that is in moral, legal, and identity-based legitimacy. Furthermore, in areas where control was contested and where the population could not be shielded from insurgent intimidation, it is argued that the effects of coercion outweighed legitimacy altogether.     

一种新的星载高分辨宽测绘带SAR运动目标

本文针对星载多通道高分辨宽测绘带合成孔径雷达系统,提出了一种地面运动目标检测和参数估计方法,该方法首先利用空时自适应处理进行杂波抑制,然后采用传统SAR成像处理得到模糊的运动目标图像,接着利用恒虚警检测技术检测出所有运动目标,包括真实目标和由于多普勒模糊引起的虚假目标,再根据模糊图像的空间位置关系从所有成像目标中检测出运动目标的真实成像位置,最后根据运动目标的斜距历程得到因运动目标速度引起的图像位置偏移,由此估计得到运动目标速度。该方法具有运算量小、检测精度高等优点,星载仿真数据验证了本文方法有效性。     

一种鲁棒的场地球类视频中的球门探测方法

在场地球类视频中,球门常常会伴随着精彩片段而出现。因此,球门探测是体育视频的基础,同时也是视频高层语义概念探测的研究热点。目前,利用机器学习方法进行视频中的对象探测是非常有前途的研究领域。基于此,提出一种基于模糊决策树的球门探测算法,用来探测场地球类视频中球门帧的出现,为了提高分类准确性,在模糊决策树训练的过程中加入了平衡处理。实验结果表明,与基于阈值和决策树的算法相比,该算法可以得到更好的分类结果(F-measure>95%),并且我们可以从所建立的树中推导出模糊规则来解释分类模型。

Winston Churchill and the third front 1

The premise of most Western thinking on counterinsurgency is that success depends on establishing a perception of legitimacy among local populations. The path to legitimacy is often seen as the improvement of governance in the form of effective and efficient administration of government and public services. However, good governance is not the only basis for claims to legitimacy, especially in environments where ethnic or religious identities are politically salient. Some experience in Iraq suggests that in environments where such identities are contested, claims to legitimacy may rest primarily on the identity of who governs, rather than on how whoever governs, governs. This article outlines the intellectual foundations of existing policy and doctrine on counterinsurgency, and argues that development and analysis of counterinsurgency strategy would benefit from a greater focus on the role of ethnic and religious identity in irregular warfare.
