针对战场通信网络的复杂性和安全性,选取3种典型通信网络为研究对象,采用离散事件驱动原理和"协议-设备-平台-网络"4层建模机制,实现了战场通信网络的计算机仿真。采用"软件定义"的思想实现了通用以太网接口的半实物接口定制,以及实物计算机和虚拟网络中的仿真节点映射及数据的交互,在此基础上构建了局域网环境内的战场通信网络入侵测试的半实物仿真系统,进行了战场通信信息截获和DDo S(Distributed Denial of Service)攻击实验,获得了统计数据和仿真结果。实验结果表明:采用分层建模机制和通用接口定制能实现网络通信半实物仿真,且结构简单、易于实现,所得结果可靠。 相似文献

AVL系统就是GIS与GPS技术集成的成功应用。AVL系统中GPS信号在GIS地图上显示时,由于各种因素的影响,存在很大的偏差。对这种偏差的校正是十分必要的。为了解决这个问题,对以前提出的误差校正算法———"线性抽象算法"进行了改进,提出了另一种误差校正方法———"缓冲区线性抽象算法",实验结果表明这种方法能在很大程度上校正偏差,不但具有较高的精度,而且还提高了算法效率。 相似文献

The war that Portugal was obliged to fight in Africa began in 1961 and immediately stretched the resources of its armed forces. Nowhere was this thinness more apparent than in policing the vast territory of Angola. The east and southeast of Angola were particularly vulnerable, as the area was a vast, sparsely populated region characterised by enormous featureless plains or chanas covered in tall grass and broken by an extensive river system and mountainous forests. The only military solution to policing these immense spaces was aviation and specifically the helicopter that could carry troops into battle, protect them with a gunship and bring them home when the operation was concluded. The immediate problem for the Portuguese Air Force (Força Aérea Portuguesa or FAP) in Angola and elsewhere was a scarcity of helicopters. The solution was an alliance with South Africa, which had a strong inventory of Alouette IIIs, to help in policing the east. This move was likewise in the interest of South Africa, as its threat came from Zambia through south-eastern Angola. This article examines the strategic and tactical development of this unusual, cross-cultural alliance and the symbiotic relationship that resulted in destruction of the enemies of both in Angola. 相似文献

In the Post-Bipolar Era the growing complexity of the military operations requires a new approach for the resolution of international crises. Since the end of the Cold War, peace support operations (PSO) have become the mainstay and principal occupation of most Western armies. At the same time, Italy has been one of the most important actors in such an area. The article focuses on the cooperation between military and civil components (a process called CIMIC) as a key variable in the Italian PSOs. We will analyse in detail the main lessons learned from past military interventions as well as the general context in which new tendencies are taking place. The maintaining of a minimum security frame becomes essential to fulfil activities ‘collateral’ to the mission: reconstructing services and infrastructure, food distribution, water and medication, law and order, de-mining, training of local forces, and supporting local institutions. These are the main tasks to obtain thrust and support from the population. 相似文献

Energy continues to serve as the bedrock of modern economies and the main driver of modern society. For Africa, the production and supply of energy resources such as crude oil, natural gas, uranium, coal, biomass, biofuels and other renewables are an important source of employment, rents, taxes, royalties and profits. This sector brings in several tens of billions of dollars of revenue annually. The production and delivery of such resources, however, depend on critical infrastructures such as pipelines, refineries, processing plants, terminals, rigs, electrical energy pylons, substations, pump stations, vessels, and tankers. These infrastructures have been attacked by terrorists, insurgents, vandals and saboteurs, all of whom see them as targets against which to register their grievances and extract concessions from the state. This paper is a chronological account of some of the documented incidents of terrorism, insurgency, kidnapping, destruction, sabotage, and human casualties suffered in the oil and gas sectors in Africa between 1999 and 2012. It is based on data extracted from the databases of the RAND Database of World Terrorism Incidents and the University of Maryland's Global Terrorism Database (GTD). 相似文献
