| 中文摘要: |
| 针对核环境的特殊性，采用无线传感器网络这种新兴技术进行核环境监测，本文提出了一种高效的分布式目标检测算法.该算法基于数据融合理论，采用层级结构设计，每个传感器节点充分利用自己和邻居节点的决策信息来做局部检测决策，决策中心根据各个节点通过无线方式传送过来的局部决策值来做出最终决策.本文对所提算法的性能进行了仿真验证，并且与已有另外的两种算法进行了比较，仿真结果表明，本文提出的算法性能优异，能够满足实际应用的要求. |
| 英文摘要: |
| This paper proposed a distributed target detection algorithm(DTDA) for radiation surveillance using wireless sensor networks.Based on the data fusion theory,the DTDA adopts a structure of three levels.Each sensor not only uses its own measurement,but also makes full use of its neighboring sensors to make a cluster-level decision.The fusion center of the sensor network will make a whole network-level decision based on the cluster-level decisions,which are transmitted to the fusion center by wireless communication.We evaluate the performance of our DTDA by simulations.Simulation results show that our DTDA can greatly improve the network decision performance,and the proposed algorithm outperforms two typical peer algorithms. |
