随着全球范围的城市化进程不断推进,未来军事斗争向城市环境中发展是必然趋势。在城市作战需求分析的基础上,剖析了传统装备的"城市病",阐述了小型旋翼无人机在城市军事行动中的应用潜能。研究表明,针对现有装备在城市作战中显示出的若干短板,发展基于小型旋翼无人机打造侦察平台与精确打击平台将是一个较好的解决方案。而运用军民融合的发展模式挖掘小型旋翼无人机军用潜力,在提升军队作战能力,降低成本均具有积极意义。  相似文献

一种基于Wiener滤波的红外背景抑制方法   总被引:12,自引:0,他引:12       下载免费PDF全文
红外图像序列中小目标的检测问题是当前的研究热点。为了检测起伏背景中的弱小目标,在理论分析的基础上提出了用Wiener滤波器去除起伏背景,然后进行自适应目标检测的小目标检测方法。采用连续采集的长波红外图像序列进行了实验研究,并给出了目标检测结果及其分析。结果表明,该算法能够从信噪比大于2.0的图像序列中检测出目标轨迹。  相似文献

小灵巧炸弹是一种采用倾斜转弯(BTT)控制方式的小型面对称电视制导航空弹药,在实际飞行中必须确保其导引头框架角不超出可用范围。针对上述问题,根据时变偏置比例导引的思想,在三维空间中设计视线角速率偏置项,通过姿态角时变修正实现框架角约束,提出了一种带导引头框架角约束的三维纯比例导引律。仿真结果表明该方法在保证小灵巧炸弹战技指标要求的同时有效减少了框架角需求。  相似文献

The period from December 1940 through to the spring of 1941 saw the British Army win a series of rapid and decisive victories over Italian and Vichy French forces in North and East Africa and the Middle East. A key feature of these operations was the extensive British use of fast-moving all-arms mobile formations utilising superior speed and mobility to out-manoeuvre considerably larger Italian formations. A number of reasons have been given for the British Army adopting this mode of warfare, but the paper contends that the best explanation is that they were an organic evolution from methods used by the British Army in ‘small wars’ throughout the early twentieth century, use of mobile ‘frontier columns’ at the operational and tactical level of war being described and recommended by Callwell himself and visible with the Army in practice in operations in India and the Middle East in particular. The inter-war period saw the combination of this model of warfare with post-First World War military technology, notably tanks, close air support and coordination by wireless. Colonial operations in this period also saw some utilisation of what would later be identified as ‘Special Forces’ – also used extensively in the Desert War – the most obvious example being Captain Orde Wingate's Special Night Squads in Palestine in 1938.  相似文献

A comprehensive maritime interdiction strategy to attack the insurgent's logistic system was a key element in the defeat of the Tamil Tigers. The campaign of maritime interdiction required the Sri Lankan Navy (SLN) to attack LTTE arms smuggling, sea piracy, and maritime terrorism. The SLN degraded the insurgency's robust maritime logistical network while also devising tactics to engage the maritime insurgents who reacted with swarm and suicide boat tactics. The efforts of the SLN forced the Tamil Tigers to confront the government's final land offensives with diminished resources, thus collapsing a three decades’ old insurgency in a matter of months.  相似文献

Peace parks are a modern means of conflict resolution through nature conservation. The Great Limpopo Peace Park (GLPP), which spans South Africa, Zimbabwe and Mozambique, was established to bring new hope to an area that is infamous for racial and political divisions, civil war and widespread poverty. This paper discusses the impact of international laws governing landmines, the current priority choices of the countries involved, and the situation in the two mine-affected countries: Mozambique and Zimbabwe. Minefields and politics are interrelated, and have an impact at local, national and international level. Using the GLPP as a case study, the article argues that although they have been presented as excellent examples of integrated biodiversity conservation and socio-economic development in developing countries, peace parks will not fulfil their main objective of promoting an image of peace in the aftermath of conflict without addressing landmine contamination.  相似文献

舰炮对海上集群小目标射击的毁伤概率   总被引:1,自引:0,他引:1  
海上集群小目标是水面舰艇面临的主要威胁之一。以单管大口径舰炮对海上集群小目标射击作为研究对象,对集群目标进行了等效处理,分析了弹种、引信和装药的选择以及效力射中的表尺分配问题,提出多表尺效力射方法,利用该方法对海上集群小目标射击的毁伤概率进行了分析。结果表明,采用该方法并使用空炸榴弹或杀伤爆破弹,可有效破坏敌运输工具,杀伤其有生力量。  相似文献

The first conceptual, theoretical treatises about small war (la petite guerre) as special operations appeared only from the middle of the seventeenth century. The term is not used in the eighteenth-century sense of ‘special operations’ in older sources. The supposed absence of any treatment of the subject is surprising considering the obsession with the ‘art of war’ in the Renaissance, but other authors attribute it to a supposed antinomy between chivalric ideals and irregular warfare. But the absence of explicit manuals on the subject is not evidence of absence of advanced reflection on this kind of operations in the Middle Ages and in Early Modern times. We should thus look elsewhere, in other genres, for writings that contain and pass on military knowledge. Epics, romances, educational and military treatises, and memoirs in fact contain elements of a theory of special operations, even though these genres differ from our conception of rationality inherited from the Enlightenment.  相似文献

When twentieth-century authors wrote about ‘partisan warfare’, they usually meant an insurgency or asymmetric military operations conducted against a superior force by small bands of ideologically driven irregular fighters. By contrast, originally (i.e. before the French Revolution) ‘partisan’ in French, English, and German referred only to the leader of a detachment of special forces (party, partie, Parthey, détachement) which the major European powers used to conduct special operations alongside their regular forces. Such special operations were the classic definition of ‘small war’ (petite guerre) in the late seventeenth and in the eighteenth centuries. The Spanish word ‘la guerrilla’, meaning nothing other than ‘small war’, only acquired an association with rebellion with the Spanish War of Independence against Napoleon. Even after this, however, armies throughout the world have continued to employ special forces. In the late nineteenth century, their operations have still been referred to as prosecuting ‘la guerrilla’ or ‘small war’, which existed side by side with, and was often mixed with, ‘people's war’ or popular uprisings against hated regimes.  相似文献
