H∞鲁棒滤波在机动目标跟踪中的应用

在交互多模型中通常使用的卡尔曼滤波器中，引入广义H∞鲁棒滤波器，以一定的精度为代价，换取满意的鲁棒性能。H∞鲁棒滤波算法可以分解为卡尔曼滤波和鲁棒化两个环节，从而形成一种基于增益失调因子的结构化分解算法。、为验证算法的有效性，进行了Monte Carlo仿真。仿真结果表明，本文算法跟踪复杂机动目标时跟踪性能有较大提高，有很好的可实现性.

The Demand for Military Expenditure in Europe: The Role of Fiscal Space in the Context of a Resurgent Russia

A variant of established work on the demand for military expenditure is developed based on a practical concept of fiscal space from the perspective of short-term government choices concerning public expenditures. A new indicator, referred to as fiscal capacity, is defined and used as a candidate explanatory variable in an empirical model of European defence spending over the 2007–2016 period. Fiscal capacity is found to outperform simpler measurements of economic conditions, notably GDP growth forecasts, in explaining changes in defence spending efforts as a share of GDP. Regarding security environment variables, the results suggest that Russia has recently come to be seen as a potential military threat by European nations, leading to defence spending increases, the more so the shorter the distance to stationed or deployed Russian forces, and particularly so by those European nations that have a land border with Russia. A prospective exercise is then carried out in order to assess the capacity of EU member states that are also members of NATO to reach NATO’s 2% goal for defence spending over a mid-term horizon.     

India’s emerging space assets and nuclear-weapons capabilities

ABSTRACT

Over the last five decades, India’s nuclear and space programs have gone through several phases, from collaboration to divorce to supportive. An interplay of two factors determined the nature of the relationship. One was the state of India’s nuclear-weapon program. The second was international conditions, especially India’s relationship with the nuclear-nonproliferation regime. In the early decades, because of the rudimentary nature of India’s nuclear and space programs, the relationship was collaborative, since the rocket technology being developed was a necessary adjunct to the nuclear-weapon program. Subsequently, as India’s rocketry capabilities and nuclear-weapon program began to mature and concerns about international sanctions under the non-proliferation regime began to grow, the two programs were separated. The Indian rocketry program was also divided, with the civilian-space and ballistic-missile programs clearly demarcated. After India declared itself a nuclear-weapon state in 1998 and the programs matured, the relationship has become more supportive. As the two programs mature further, this relationship is likely to deepen, as the nuclear-weapon program requires space assets to build a robust and survivable nuclear deterrent force.
