声尾流自导鱼雷导引策略仿真与优化

在分析尾流几何模型及其气泡分布密度的规律的基础上,首先建立了较贴近实际的尾流声学仿真模型。其次,按照尾流自导检测流程,基于反射系数推导了尾流层及海面气泡层的回声级模型,由此建立了鱼雷声学自导检测模型。随后,根据研究需要设计了基于鱼雷作战使用评估理论的声尾流自导鱼雷仿真系统,该系统能够真实模拟尾流自导系统工作过程及鱼雷水下运动过程。最后,以该仿真系统为依托,实现了声尾流自导鱼雷应对空穴或断层的修正导引策略的仿真优化。应用结果表明:该研究对于尾流自导鱼雷导引策略优化和尾流自导仿真方法研究具有实际应用价值。

SINS/CNS组合导航的导航星表构建方法

构建满足完备性、精简性和查询快速性的导航星表是实现捷联惯性/星光组合导航系统的重要前提和保证。以天文学中的Tycho-2星表作为导航星表的初始星表,对球矩形分区方法进行了改进,包括明确分区及子分区的划分方法,提出了备选导航星的选择策略。实验结果表明,采用改进型球矩形分区方法的备选导航星数量最多只占赤纬带法导航星的19.37%,仅占全天遍历法导航星的3.12%。因此,改进型球矩形分区方法更加精准,查询更快捷,更适用于捷联惯性/星光组合导航系统。     

From the sea to outer space: The command of space as the foundation of spacepower theory

Colin Gray once lamented the absence of a ‘Mahan for the final frontier’ and spacepower theory in strategic studies. This article proposes the command of space as the fundamental concept of spacepower theory, and that Mahan himself has much to offer in the endeavour of spacepower theory-making than has hitherto been realised. The theory is advanced by tempering versions of the ‘command of space’, stressing its educational intent, and explaining the nuanced sub-concepts of space control and denial through understanding some precedents set by seapower theory. In the process, aspects of Mahanian and Corbettian seapower theory are unified.

The Afghan model in northern Iraq

In Operation ‘Iraqi Freedom’, as the Coalition's heavy forces fought in the South, in the North a handful of special operations forces, working with Kurdish rebels, clashed with the Iraqi army along the Green Line. In operations reminiscent of those used a year earlier to defeat the Taliban in Afghanistan, the lightly armed and heavily outnumbered Coalition forces called in air strikes to defeat Iraq's regular and Republican Guard army divisions. This article tells the story of these operations and discusses some of their implications for future US military policy. The success of the Afghan model in Iraq goes a long way toward demonstrating the efficacy of new air-heavy tactics and shows the strategic value of using light indigenous allies to replace heavy US land forces in both conventional combat and occupation operations.     

Westmoreland was right: learning the wrong lessons from the Vietnam War

Fourth Generation Warfare is a theory of contemporary warfare that posits a number of different ideas that are able to shed light on current conflicts. Whilst much of the debate has been concentrated on the linear development of warfare and also on analysis of the current situation of US forces in Iraq, it has resonance for a number of different conflicts taking place in Africa, if only because the US has become involved in contemporary conflicts in Somalia and the Mahgreb. There are clearly significant issues with the US-centric, flawed linear approach to history, but the actual analysis of modes of warfare has much to offer policymakers in a continent that is under-represented in the literature, and is also in danger of being forgotten in the shadow of analysis of Iraq. This paper moves on from criticising the stepped approach to history and looks at patterns of warfare in contemporary Africa, arguing that there is much in the theory that could be used to explain seemingly illogical tactics or patterns, and thus has much to tell policymakers engaged in conflict analysis.
