基于图像和惯性的头盔组合跟踪原理

不同体制的头盔跟踪定位技术单独使用时都存在一定的原理性性能制约,提高跟踪定位技术整体性能的有效途径是采用组合跟踪。目前综合性能较好的是图像式头盔跟踪,图像式跟踪技术精度高,输出数据平稳,稳定性好,但其缺点是头盔活动范围受制于CCD摄像机视场及头盔大角度转动时头盔本身对CCD摄像机视角的遮挡。惯性跟踪不需要任何外来信息也不向外辐射任何信息,可在任何介质和任何环境条件下实现360°全范围头部跟踪,但其定位精度随时间下降。提出的基于图像和惯性的头盔组合跟踪技术充分利用图像跟踪精度高、长期稳定性好及惯性定位跟踪范围广、跟踪系统简单的优点,达到单个跟踪定位体制不具备的综合性能。     

基于噪声调相干扰寄生扩频的隐蔽信息传输

在常见的各种信息隐蔽传输方法中,宿主载体大多集中于图像、音频、视频等各类多媒体信源,而通过射频信号作为载体来实施隐蔽信息传输的技术手段十分缺乏。针对这一情况,提出了一种基于噪声调相干扰寄生扩频的隐蔽信息传输方法。在干扰机对雷达、通信等目标对象发射噪声压制干扰信号的同时,将需要传输的信息寄生调制于噪声干扰的相位分量,形成一种类扩频传输信号,并有效隐藏于大功率干扰信号之中实现传输。在接收端通过解扩处理而恢复出隐藏的调制分量,最后解调出其中所隐蔽承载的数字比特流。仿真试验结果显示了该方法的可行性与有效性,这对于电子对抗设备的综合一体化应用和隐蔽通信的实施提供了新的技术途径。

European defence industry consolidation and domestic procurement bias

How have European cross-border defence industrial mergers and acquisitions affected domestic procurement bias among the major EU powers? This article departs from the findings of Andrew Moravcsik more than two decades ago suggesting that major West European states had no ingrained preferences for defence industrial autarchy. When cross-national armament projects were derailed, this could be attributed to political efforts of national defence industrial champions favouring purely domestic projects. As former national champions join pan-European defence groups, their preferences are likely modified. Does this shift procurement towards non-European “off-the-shelf” solutions which, according to Moravcsik, are favoured by defence departments? Or does it give impetus to a stronger preference for European as opposed to domestic systems? In this article, procurement patterns in the aftermath of cross-border defence industry consolidation will be analysed. Procurement bias is assessed in two industry segments characterised by pervasive consolidation.

Dealing with the fast-changing environment in the eastern DRC

This paper is a study of the phenomenon of trans-border ethnic relations and its impact on national integration and citizenship in the countries of West and Central Africa where trans-border ethnic groups exist. Despite the existence of many such groups in these regions, and the numerous problems associated with the continued relations among these groups across their countries of abode, the phenomenon has not been seriously studied, especially as it concerns the identification of members of such groups and how they are viewed by members of other ethnic groups, as citizens of one country or the other. This paper notes that trans-border ethnic solidarity ordinarily presents the relevant African states with two possibilities, namely: enormous benefits accruing from regional integration and cooperation among states harbouring fractions of trans-border ethnic groups; or, debilitating conflicts within and between these states. It is the reality of the latter possibility that this paper examines. The states and the international system are often incapable of containing this phenomenon of trans-border ethnic solidarity and usually respond in hostile ways, ultimately manifesting in citizenship problems. The study shows, however, that what is needed is not conflict but cooperation – within and between states having fractions of a trans-border ethnic group, and within the international system, for the enhancement of national citizenship and development in West and Central Africa.
