云模型和特征辐射源信息的平台目标识别

平台目标识别一般分为两个步骤,首先是对平台上辐射源的识别,然后通过辐射源和平台的关联进行平台识别.在辐射源识别阶段提出利用云模型描述和处理参数存在区间模糊和观测具有噪声的数据,较好地解决了对于带有复杂调制信号的辐射源识别问题.在平台识别阶段,就辐射源和平台关联的各种结果给出了新的计算样本和模板间匹配度的方法,并且提出利用平台的特征辐射源信息对平台识别结果进行进一步的筛选,以提高识别率.最后用仿真验证了该方法的有效性.

US paramilitary programs in comparative perspective: CIA,the US Army Special Forces,and the question of organizational form

Assumed in the long-standing debate over which agency, CIA or the Department of Defense, should conduct US paramilitary operations is the idea that these organizations’ paramilitary programs are fundamentally the same kinds of things. This article questions that assumption by investigating the organizational forms underlying these agencies’ paramilitary programs in four empirical cases drawn from South Vietnam and post-9/11 Afghanistan. A typology is constructed around two identified organizational forms: “franchising” for CIA vs. “company ownership” for the US Army Special Forces. Different paramilitary organizational forms are found to have significant operational implications that should inform the paramilitary transfer debate.     

What is the global landpower network and what value might it provide?

US national security guidance, as well as the US Army’s operational experiences since 2001, emphasizes the importance of working closely with partner countries to achieve US strategic objectives. The US Army has introduced the global landpower network (GLN) concept as a means to integrate, sustain and advance the Army’s considerable ongoing efforts to meet US national security guidance. This study develops the GLN concept further, and addresses three questions. What benefits can the GLN provide the Army? What are the essential components of the GLN? What options exist for implementing the GLN concept? By developing the GLN concept, the Army has the opportunity to transition the GLN from an often ad hoc and reactive set of relationships to one that the Army more self-consciously prioritizes and leverages as a resource to meet US strategic objectives.

针对GM(1,1)预测模型误差较大的问题,在GM(1,1)模型的基础上引入加权马尔科夫模型构建了部队集成训练效果预测模型。该模型以GM(1,1)模型存在的预测残差作为划分马尔科夫状态的依据,通过加权处理对预测结果进行修正。实例分析结果表明,该模型算法简单,易于实现,可以较大地提高部队训练效果预测精度,为部队开展科学有效的实战化训练提供了有力的数据支撑。     

Rényi信息增量和协方差联合控制的多传感器管理算法

针对目标跟踪中雷达组网场景下多传感器管理问题,结合Rényi信息增量和协方差两种算法各自特性,利用并行处理的思想提出了一种基于Rényi信息增量和协方差联合控制的传感器管理算法。在具体仿真设计环节,分为传感器跟踪能力大于目标数和传感器跟踪能力小于目标数两种场景。仿真结果表明该算法在单目标匀速、多目标匀加速等多数场景下能够对目标进行有效跟踪,同时降低了传感器的切换频率,具有更好的实时性。     

一种确定检测时间的方法

在许多作为侦察用的无源传感器只报出其检测结果时,利用此传感器一系列检测报告确定被检测目标何时进入及何时离开此传感器检测区域,成为解决决策级信尽融合问题的关键。本文讨论了一种利用序贯分析方法计算检测时间的近似方法。
