Radiation Source Localization System Based on Wireless Sensor Network

根据剂量率与距离平方呈反比的原理,设计并实现一种基于无线传感器网络的辐射源定位系统。介绍系统总体网络模型、辐射传感器和长距离无线通信节点的设计方案。通过锚节点自身携带的GPS和辐射传感器获取地理位置和辐射值,根据定位模型实现辐射源定位。实验结果表明,该系统简单有效,定位精度小于3 m,误差在1%以内。

This paper constitutes a localization model which is based on that dose rate is inversely proportional to square of distance, proposes and implements a scheme which is based on Wireless Sensor Network（WSN）. It introduces the Overall system network model, radiation sensors and long-distance wireless communication node design. It gets anchor nodes＇ locations and radiation values with radiation sensors and GPS sensors to implement radiation localization. Experimental results show that the method system is efficient, and the location accuracy is less than three meters.
