基于电控罗经实测数据,对实时数据进行时间序列建模,并对模型进行了处理,分别采用鲁棒Kalman滤波器和标准Kalman滤波器,并对这两种滤波器进行了对比,从数据的光滑性和滤波器的最优估计角度得出鲁棒Kalman滤波器对于数据处理具有良好的适用性。 相似文献

水雷战是利用水雷武器和反水雷装备进行封锁和反封锁作战的海战样式。台“国防部”202年7月23日公布的新版《国防报告书》中称,在制海作战部分,“未来将建立三度空间的完整反封锁能力、布雷能力和开放国际安全航道扫雷的水雷作战能力。”台军认为,未来一旦发生台海战事,攻方可能采取海空封锁、三栖攻台的作战模式,其中海上封锁的手段包括采取水雷封锁,因而水雷作战将是海上作战的重头戏。台军为了争夺台岛周边50海里的“制海权”将竭力消除攻方布雷封锁,另一方面将施放布雷进行反封锁作战。 相似文献

作战效果的评估结论在作战过程中的作用非常重要,直接影响后续作战行动的进行。在该文中,采用了一种新颖的基于关键指标的模糊综合评判法来评估作战效果。首先根据作战预期目标确立指标体系中的关键指标,通过定量或定性的方法完成关键指标的评估,形成初步结论。然后完成指标体系中次要指标的评估,进一步丰富评估结论,提升评估结论的准确性。 相似文献

This chapter presents a summary of the findings of the workshop on ‘Analytical and Institutional Methods and Frameworks’. The paper discusses the nature of the analytical methods used in the papers presented and the purposes for which they were employed, which were generally to either assist in the planning and operation of public transport or to monitor the efficiency and effectiveness of transport services. Subsequent sections examine issues related to data collection and management, and the more general issue of institutional arrangements. Policy and research agendas needed to support further consideration of the subject are then identified. 相似文献

This paper explores the current state of coastal and inland shipping in Tanzania. It provides an overview of the state of ports and shipping in Tanzania, and the reasons underlying the present crisis of competitiveness in terms of both global pressures and national and regional dynamics. Problems of competitiveness are at least partially due to under-investment, management failures, skills shortfalls and difficulties in interfacing with the railway network. Less easy to resolve structural problems include the great imbalance between imports and exports, heightened regional competition and ongoing political instability in the Great Lakes region. 相似文献

As the controversy over Outer Continental Shelf (OCS) oil and gas leasing continues, with environmentalists and fishermen seeking to block or delay leasing decisions that they think will adversely affect their interests, the need for better estimates of the environmental costs associated with OCS development becomes increasingly apparent. Although high degrees of precision in such estimates may never be economic, let alone feasible, better knowledge would reduce the uncertainty surrounding the magnitude of such costs, and would make it easier to come to grips with the problem and reduce, if not resolve, the controversy. 相似文献
