Given the nature of global counterinsurgency operations, the demands of military expansion, and the need for cultural, linguistic, and regional expertise, the United States Army should evaluate the establishment of US-led foreign troop units for its evolving force structure. This article proposes the creation of an American foreign legion based upon the recruitment of US-led, ethnically homogeneous tribal force units to meet the grist mill of counterinsurgency operations. This structured approach would be more beneficial than the current reliance on a de facto American Foreign Legion, represented by private military contractors (PMCs), many of them comprised of foreigners. These PMCs carry a number of oversight, accountability, and legal risks not found in a fully integrated, and US-officered foreign legion. The British Brigade of Gurkhas, the South-West African Police Counter-Insurgency Unit (Koevoet), and the Kit Carson Scouts serve as relevant historical examples where foreign troops were used to supplement national manpower resources. 相似文献

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. 相似文献

潜器进入匹配区时捷联系统已积累了一定的误差,有效利用匹配信息对误差进行修正是保证后续航行精度的基础;通过建立水下地形匹配辅助导航系统误差模型,以地形匹配模块和深度压力传感器测量的位置信息和深度作为量测量,设计了卡尔曼滤波器。仿真研究证明:所设计的滤波器具有良好的估计精度;同时,通过设计潜器航行动作证明了相关误差量的估计效果与潜器运动激励有关,为匹配区内进行误差估计时潜器所采用的运动状态提供了参考。 相似文献

提出了一种基于地形的小波场特征的相关匹配的方法.在小波场的相关匹配技术中,由于小波的垂直分量和水平分量反映了图像的边缘等高频信息,所以分解后的小波特征场相关性小,有比较高的匹配精度;同时,由于数据量压缩,提高了匹配速度,适应于地形匹配的快速实现. 相似文献

介绍了一种利用局部沃尔什变换(LWT)提取图像纹理特征的新方法,给出LWT的定义,并分析了LWT系数的统计特性及其各阶矩的纹理鉴别性能。结果表明:自然纹理图像的LWT系数一般不服从正态分布,其偶数阶矩具有较好的纹理鉴别性能,奇数阶矩的纹理鉴别性能较差,因此选取LWT系数的偶数阶(2、4、6阶)矩作为纹理特征。与Haralick[1]、Wang和He[2,3],以及HuiYu[5]等人提出的纹理特征相比,基于LWT的纹理特征具有更好的鉴别性能,并且计算简单。 相似文献

为解决飞机在低空突防过程中的雷达地形遮蔽盲区快速计算问题,提出了一种基于转盘爬虫对象的快速算法。首先介绍了雷达盲区产生的因素,分析了地形遮蔽和地球曲率盲区的计算模型,然后定义了转盘及爬虫对象,并设计了基于转盘爬虫对象的地形遮蔽盲区计算方法和流程。在此基础上,将雷达地形遮蔽盲区计算结果进行三维建模及可视化,通过典型算例对算法进行对比测试和实验,得到不同高度的雷达地形遮蔽盲区分布图及三维可视化模型,证明了算法的快速性和可行性。 相似文献
