现代机载探测系统多源信息融合算法

针对机载探测系统的特性,应用Dempster-Shafer(D-S)证据理论和主观Bayes的组合算法,对来自机载SAR雷达、机载前视红外搜索跟踪系统(IRS)、电子支援系统(ESM)等探测系统多次观测所获得的数据,以及来自地面的电子情报(ELINT)的不同信息进行实时融合、识别,进而确定攻击对象.通过实例进行仿真证明,这种组合算法适用于不同类传感器和不同格式信息间的融合,适合于复杂信号环境.     

确定性理论在雷达型号识别中的应用

雷达型号识别是雷达对抗情报侦察的首要工作,是近一步分析雷达用途及相关武器系统的基础,也是高层次上的态势评估和威胁估计的主要依据.针对现代战争中电磁信号环境的复杂性,利用单一传感器很难对雷达型号进行准确识别,而基于确定性理论的不确定推理技术能将多个传感器在多个周期的侦察信息进行融合,所以采用确定性理论的数据融合技术,基于确定性理论的组合规则,采用分层式融合算法对雷达型号进行识别.仿真结果表明,该方法的识别结果令人满意,使采用单一传感器可能存在的无法识别或误识别等现象得到了明显的改善.

Book reviews

Jurgen Brauer's comment presents what he calls a replication of an earlier study by Higgs and Kilduff (1993) and uses it to criticize the adequacy of the Higgs‐Kilduff model. In several respects, however, Brauer has not actually performed a replication: he uses different data, a different sample period, and arrives at different results. His criticisms rest on his own setup, not that of Higgs and Kilduff. Therefore they have no strict applicability to the latter. Moreover, Brauer's stepwise model has no bearing on the Higgs‐Kilduff model, as it violates that model's specification requirements.     

THE CASE FOR DEFENCE

What is the case for defence and is it a worthwhile investment? This question is addressed for two contrasting nations, namely, the UK and New Zealand. Economists have a set of standard analytical tools for addressing the question but they are difficult to operationalise. This paper provides policy‐relevant answers.     

A simple and untraditional analysis of western alliance burden‐sharing

The original Olson and Zeckhauser model of alliance burden‐sharing was based on the following four assumptions: (1) alliance defence is a pure public good; (2) allied nations make their security contribution decisions without consulting the other allies; (3) alliances produce only a single public good; and (4) alliance defence is produced with equal degrees of efficiency in all alliance nations. But while the first of these assumptions has received a great deal of attention in the alliance literature, the remaining ones have received comparatively less attention, particularly in terms of empirical analyses. This paper synthesizes a varied literature developed around these four assumptions, both substantively and theoretically, and shows that when these assumptions are brought closer to real world approximations, hypotheses regarding the potential for security cooperation with less free‐riding result. This article also provides a simple test of Western alliance burden‐sharing in the areas of military spending, development resources spending, and research and development spending that supports the hypothesis positing more equitable burden‐sharing.
