舰载被动传感器数据关联算法研究 总被引:2,自引:0,他引:2
针对ESM的属性关联和空间关联准确度不高的问题,提出了一种属性-空间综合关联算法。建立了属性-空间综合关联算法的功能模型,并对采用算法进行了描述和仿真。仿真试验结果表明,属性-空间综合关联能有效克服不同平台、相同目标属性关联和同一平台、不同辐射源空间关联存在的问题,且具有较高的关联准确度。 相似文献

针对无线传感网中高效数据收集和传输的需要,提出了一种基于动态可调簇的能量感知数据收集协议ACEDGP(Adjusted Cluster-based energy-aware Data Gathering Protocol)。该协议初始时根据区域将节点等分成许多簇结构,簇首节点负责簇内部数据的收集和聚合,距离较远的簇通过其他簇首节点的转发实现数据的收集;随着时间的推移和节点能量的减少,ACEDGP能够统计各簇首能量消耗预测簇的通信频次,根据动态调整簇策略选择合适的簇首节点和合并分裂各个相邻的簇,保证各簇首节点簇内数据收集和簇间数据转发的能量平衡。仿真结果表明,与典型的分簇协议相比,ACEDGP能够更好地平衡节点的能耗,获得更长的网络生存期。 相似文献

ABSTRACTThis paper examines the importance of closer co-operation in defence-related procurement. Led by the decision that Belgium will lead the procurement of 12 Mine CounterMeasures Vessels (MCMV), the case of a potential Belgian naval construction cluster is discussed. The feasibility of a potential cluster is investigated by looking at key elements of a successful naval construction cluster, the Dutch naval construction cluster, and comparing those key elements to the current Belgian situation. Forming a sustainable Belgian naval construction cluster will be difficult. Most of the procurement process of the MCMVs is set on a European tender. In the long run, due to the absence of both a launching customer and leader firms, no party is able to carry the cluster with investments and knowledge spill-overs. In order to keep public support for large defence-related investments, clustering around the MCMV integration system and proactive cluster support is recommended. 相似文献
