北斗双星系统车辆定向技术

基于卫星载波相位干涉测量原理,研究了利用北斗双星系统确定车辆航向的相关技术。首先建立了北斗定向的数学模型;接着讨论了基于交换天线思想的等效转动基线极大/极小值ERMM模糊度确定方法;然后利用构建的双天线定向系统设计了车载实时航向确定实验,并通过高精度激光陀螺捷联惯导系统对航向确定精度进行了校核。实验结果验证了ERMM解模糊方法的有效性,表明定向系统实时航向确定有效精度可达0.62°。研究结果表明,北斗双星系统可以用于实时确定车辆的航向。     

使用保障资源的确定方法探讨

在使用保障过程中需要9项使用保障资源,包括人力与人员、保障设备、技术资料、训练与训练保障、计算机资源保障、保障设施、储存和运输、能源、弹药等。其中人力与人员、使用保障设备2项内容与使用保障联系最为紧密,在装备的研制阶段就应考虑确定。主要讨论了用相似系统法确定人力与人员的数量,用排队论确定保障设备的品种和数量。

作战系统MAS中的作战行动域与实际组元逻辑关系分析

建立作战系统多Agent系统(Multi-Agent System,MAS)组织,必须首先建立由作战系统实际组元到Agent的映射。围绕作战系统MAS的建立,在提出由作战系统实际组元到Agent的映射过程与方法的基础上,提出了作战系统领域概念视图、作战行动域及其各层次概念、实际组元逻辑关系分析的基本方法,为实现基于多Agent的作战系统建模与仿真奠定基础。在基于多Agent的信息化战场多传感器仿真演示系统中,证明了该方法的可行性与有效性。     

The Naval Intelligence Underpinnings of Reagan's Maritime Strategy

Washington's so-called Maritime Strategy, which sought to apply US naval might against Soviet vulnerabilities on its maritime flanks, came to full fruition during the 1980s. The strategy, which witnessed a major buildup of US naval forces and aggressive exercising in seas proximate to the USSR, also explicitly targeted Moscow”s strategic missile submarines with the aim of pressuring the Kremlin during crises or the early phases of global war. Relying on a variety of interviews and newly declassified documents, the authors assert that the Maritime Strategy represents one of the rare instances in history when intelligence helped lead a nation to completely revise its concept of military operations.     

China's Naval Ambitions in the Indian Ocean

This article argues that an increasingly sea-power-minded China will neither shelter passively in coastal waters, nor throw itself into competition with the United States in the Pacific Ocean. Rather, Beijing will direct its energies toward South and Southeast Asia, where supplies of oil, natural gas, and other commodities critical to China's economic development must pass. There China will encounter an equally sea-power-minded India that enjoys marked geostrategic advantages. Beijing will likely content itself with ‘soft power’ diplomacy in these regions until it can settle the dispute with Taiwan, freeing up resources for maritime endeavors farther from China's coasts.     

卫星双向与单向载波联合的北斗星载钟短稳评估方法

卫星导航系统评估星载钟稳定度通常需要大型地面监测网的观测数据和复杂的钟差确定算法,不能基于单站观测数据实现。论文在分析利用单站观测数据评估星载钟短稳方法的基础上,提出了一种相对容易实现的联合卫星双向载波测距值与GNSS单向载波观测值的星载钟短稳评估方法。该方法通过卫星双向载波测距确定星地几何距离,基于消除星地几何距离的GNSS接收机载波相位观测值估算卫星相对钟差,进而实现其短稳评估。利用北斗系统观测数据进行了有效性验证,并与复杂钟差确定算法以及利用平滑广播星历的方法(SBE法)进行了对比,本文方法与复杂钟差确定算法计算的结果相符,在1000s平滑间隔内与SBE法结果一致,相对误差小于10%,1000s以上好于SBE法。     

Investigating optimal replacement of aging air force systems

An availability‐oriented approach has been developed to decide when to replace an aging system. For an existing system, it is optimal to operate another year if and only if the incremental cost per available year is less than the lifetime average cost per available year of a new aircraft. We illustrate our approach using United States Air Force KC‐135 tanker data. In demonstrating our approach, we find it will be optimal to replace the KC‐135 by the end of the decade.     

ANGOLAN DEADLOCK

Children on the African continent have suffered immensely from the proliferation and misuse of small arms, including death, injury, displacement, separation from families, loss of access to health, humanitarian and educational services, and lack of economic opportunities. Further, over 300,000 children serve as child soldiers, relying on small arms as their tools of war. The international community has worked to establish protections for children for over 50 years, yet children continue to suffer. The recent UN Special Session on Children adopted ‘A world fit for children’, which, in combination with the Programme of Action agreed upon at the July 2001 UN Conference on Small Arms, begins to address a comprehensive approach to eliminating the negative impacts of small arms proliferation on children in conflict.
