BM早期预警相控阵雷达跟踪能力分析

弹道导弹（BM）跟踪是BM防御中的关键问题,分析BM早期预警相控阵雷达的跟踪能力具有重要意义。文章首先分析了预警体系中各传感器单元间的信息流程,解算了早期预警雷达与后续跟踪雷达交接班的需求特性,在分析早期相控阵预警雷达的工作流程的基础上,解算了不同距离需求时雷达可分配跟踪波束数目,给出最大跟踪能力模型,并对比常规的波束控制模式,仿真计算了两种波束分配模式下雷达的稳定跟踪能力。通过Matlab仿真结果分析,验证了雷达对BM目标的跟踪能力。     

一种水面舰船对空自防御作战能力计算模型

在基于集中指挥的舰船对空自防御作战中,目标指示时间对目标的拦截次数有较大影响。为精确反映目标指示时间对拦截次数的影响,建立了集中指挥方式下的舰空导弹拦截次数计算模型。首先,根据集中指挥方式下的对空自防御作战过程,得到单发射单元对目标拦截次数的模型,然后将多发射单元对目标拦截次数计算问题转换为多个单发射单元对目标拦截次数计算的问题,从而得到多发射单元对目标拦截次数的模型。对不同目标指示时间、雷达跟踪距离、发射单元数条件下的拦截次数进行计算,结果表明,计算模型能够反映目标指示时间、雷达跟踪距离以及发射单元对拦截次数的影响。

太空惊雷 反导硬杀伤武器的发展及中国反导试验

近日,中国政府对外宣布成功进行了弹道导弹中段拦截试验。从中国本土发射的拦截弹击中了先期发射的目标弹,据信拦截弹与目标碰撞的高度已经超过大气层高度,技术上已达到在外层空间用动能拦截弹进行导弹拦截试验的先进标准。由此,中国成为继美国之后世界上第二个进行导弹中段拦截试验的国家。继此前的2007年1月11日使用拦截弹成功摧毁了报废的人造卫星之后,中国仅用3年的时间就进行了导弹中段拦截的实弹试验,表明中国在反导/反卫星作战系统的研究和试验方面拥有很强的技术和综合能力。虽然本次反导试验还没有做到实战条件下拦截陌生目标的要求,但已经在技术上实现了从打卫星到打导弹的进步,中国自主建设国家导弹防御系统的努力距实战部署又前进了一大步。中国政府在导弹拦截试验后宣布该试验不针对任何国家,这与中国承诺不首先使用核武器一样都是防御性的宣示,是中国依靠导弹核武器建立有限的战略威慑和反击能力的同时,在防御核攻击的军力建设上所采取的合理有限的装备发展措施。导弹防御系统尤其是拦截弹道中段导弹目标的武器必然要进入外层空间,大气层外的武器拦截试验显然不符合太空非军事化的国际共识,但在美国政府推动导弹防御系统发展和其他国家部署的情况下,中国依靠自己的力量发展规模有限但满足实际需要的导弹防御系统,是中国保持独立自主国防政策和维护国民经济快速发展的基础保证。太空非军事化是中国和全世界爱好和平人民的共同愿望,但必须有足够的实力支持才有实现这个愿望的可能。中国古代军事家就已清楚地认识到"只有能战方能止战",不在太空军备竞赛中占据自己的地位就没有最终实现和平利用空间的可能。中国发展反导防御系统的目标是维护自身的安全,这套武器系统的存在不会对任何国家造成威胁,在实现最终目的的过程中也不需考虑其他国家或团体发出的不同声音。

Recent progress on wave induced loading measurements in warships

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.
