ARUAV前沿判别法抗多点源诱偏性能研究

基于反辐射无人机的时域鉴别技术,提出了一种以小波分析为手段的前沿判别法。将被动雷达导引头使用固定波门对脉冲前沿进行采样所得的信号作小波分析,对分析结果进行判定,当判定采样信号内为单辐射源信号时对其进行测向、测频、跟踪和打击。针对两点源诱偏系统分析表明,在大部分空域中,反辐射无人机总是能首先跟踪诱饵信号。通过建模与仿真,验证了前沿判别法能够有效对抗两点源诱偏系统,并由固定波门得到了有效的判别空域。

Capitalism & the “new wars”: free markets and societal insecurity before and after the cold war, 1970–2013

Critics of globalisation suggest that growing free-market conditions generate anomie, leading ultimately to what some term ‘new wars’ and new insecurities. Others argue that liberal economies dissuade violence since people gain from peace. This study argues for a micro perspective that views predatory economic policies driving higher investment in rebellion-specific capital, such as shadow economic activity that easily translates into insurgency in weak-state settings. Investment in the shadows determines survivability against superior state forces, and survivability determines rebellion, by definition. Using civil war onset data from 1970 to 2013, as well as the Global Peace Index (GPI) and several of its individual components, which capture societal insecurity above and beyond the absence of armed violence, this study finds that countries that are more capitalistic have a lower risk of civil war and societal insecurity. The results are robust to alternative models, testing methods, and uphold when examining several relevant subcomponents of the index, such as internal conflict, violent crime, homicides, ease of access to small arms, and political instability. Surprisingly, democracy tends not to be associated with peace but associates with increased criminality whereas strong autocracy reduces it, suggesting that capitalism, more than democracy, associates with conditions favourable to societal security, independently of a country’s level of development.

Winning hearts and minds: legitimacy in the Namibian war for independence

Efforts at winning hearts and minds (WHAM) impact on and are affected by perceptions of legitimacy. In the Namibian war for independence (1966–1989) efforts of the South African counterinsurgent forces at winning hearts and minds focused mainly on persuading the population to cooperate in exchange for material benefits and services. The article demonstrates that this successfully contributed to a dimension of legitimacy that is conceptualized as pragmatic legitimacy. However, other dimensions of legitimacy are identified in which the South Africans were lacking, that is in moral, legal, and identity-based legitimacy. Furthermore, in areas where control was contested and where the population could not be shielded from insurgent intimidation, it is argued that the effects of coercion outweighed legitimacy altogether.     

Defence Transformation in South Africa: Sharing the experience with the Forces Armées de la République Démocratique du Congo

“There is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle than to initiate a new order of things. For the reformer has enemies in all who profit by the old order, and only lukewarm defenders in all those who would profit by the new order”—Machiavelli

This essay was written after a team of the Institute for Security Studies visited the Democratic Republic of the Congo (DRC) to share their experiences of the challenges of defence transformation with Congolese officials and members of civil society.

It discusses the South African defence transformation process and experience in detail and highlights the imperative for visionary leadership, commitment and communication as prerequisites for successful transformation. The DRC faces a unique opportunity to design and create an optimal national defence force for itself, which will reflect its new and evolving national policy on defence, and therefore the needs of the nation. This poses an exciting challenge and true opportunity to move beyond survival into a new age. The essay aims to make a contribution to this process.     

‘God willing,I will be back’: Gauging the Truth and Reconciliation Commission's capacity to deter economic crimes in Liberia

Recently, in July 2012, the high-profile and bitterly fought nine-month race for the post of Chair of the African Union (AU) Commission, between Dr Jean Ping of Gabon, and his main challenger, Dr Nkosazana Dlamini-Zuma, culminated in the latter's victory. Her victory came after the deadlock at the Eighteenth AU Summit in January 2012. Borne out of the considered need for a quick fix through reliance on a vote of expediency, the election of Dr Dlamini-Zuma represented a political resolution to the crisis that arose due to the earlier ongoing electoral deadlock. Far from being a competitive election by design, the 2012 AU Commission election by default became transformed into an intensely fought campaign that put the AU in the limelight. This article briefly introduces the electoral process, explains in detail the voting behaviour of AU member states, and offers five specific reasons for the victory of Dr Dlamini-Zuma. On the surface the election looks very competitive, but the article explains why this is not the case. To create greater competition for these posts, the AU needs to overhaul the nomination process and the voting procedure. In this regard, the article proffers detailed analysis and proposes a radical revision of the existing criteria for the nomination. The article also proposes specific recommendations for the amendment of the rules of procedure of the AU Assembly to allow for a qualified majority as a deadlock breaker in the fifth round. It also assesses whether the integrity of the AU Commission election was damaged during the campaigning and voting process. In this regard, it recommends the development of a code of conduct for future elections at the AU.
