干扰条件下空中目标识别方法研究

目标识别是态势评估和威胁估计的基础,是作战指挥辅助决策的重要依据,是防空作战的关键环节之一。该文将雷达信息可信度扩展到传感器信息可信度,并基于扩展内涵的目标识别信息可信度,提出一种应用对空侦察雷达、光学器材、ESM传感器的空中目标识别方法,完成干扰条件下空中目标识别模块的设计。该方法依靠目标识别信息可信度较高的传感器信息来做出全局判决,有助于提高整个系统目标识别的可靠性。

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。

Leadership and national security: an interrogation of the Boko Haram violence in Nigeria

This study contends that an analysis of the nexus between leadership and security offers useful insights into explaining conflict by stating that the conceptualisation of these argots, especially through the definition of leadership as a process, helps to explain and address Nigeria’s security challenges. By arguing that leaders’ ability to establish mutuality with their followers in any situation and set collectively-generated means for attaining these set goals for societal security, the study shows how such a relationship creates a secured state. This is not the case in Nigeria, where leaders’ security decisions are influenced by external actors rather than by their followers. By showing that the Nigerian ruling elite’s security agendas intersect with dominant global notions of security while neglecting genuine security interests of ordinary Nigerians, the study contextualises the complex global and local security interests in Nigeria. The lack of an intersection at home, however, has contributed to the emergence of extremists such as the Boko Haram sect, as well as the escalation of the acts of violence they perpetrate. As national insecurities become complex and intractable, ‘elegant’ or unilinear solutions – such as a military approach – lack the capacity to address these problems.     

Too much Western bias? The need for a more culturally adaptable approach to post-conflict security sector reform

The existing guidelines for security sector reform (SSR) tend to draw on theoretical work in the field of civil–military relations, which in turn has been derived from Western, liberal democratic models of governance. Although guidelines strongly advise that local culture and context need to be considered when drawing up objectives for post-conflict SSR programmes, this is not often reflected in practice. This article considers some of the reasons for this, citing both in-country challenges and donor-related issues, and suggests that one of the biggest problems is a lack of alternative, non-orthodox models of civil–military relations to draw upon. It is further suggested that elements of suitable alternative models may be found in states which possess political structures not entirely dissimilar to the Western, liberal democratic ideal, but which can offer different perspectives. Detailed research of these structures should produce a pool of sub-models which could then be employed to create bespoke, culturally appropriate objectives for use in post-conflict SSR programmes.

Security sector reform in Africa: Donor approaches versus local needs

Many African states have security sector reform (SSR) programs. These are often internationally funded. But how do such programs account for previously existing security institutions and the security needs of local communities? This article examines SSR all over Africa to assess local ownership and path dependency from a New Institutionalist perspective. It finds that SSR, particularly in post-conflict countries, tends to be driven by ideas and perceptions of international donors promoting generalized blueprints. Often, such programs only account in a very limited way for path-dependent aspects of security institutions or the local context. Hence, the reforms often lack local participation and are thus not accepted by the local community eventually.
