摘要
针对常用安检技术对液体危险品检测存在效率低等问题,提出一种利用散射参数曲线特征识别液体危险品的方法.厘米波通过介电常数和粘稠度有区别的液体时,相应散射参数曲线的特征有所不同.利用超宽带技术收集大量的采样点以达到精确描述散射参数曲线的目的.感知机模型通过识别散射参数曲线的特征对待测液体的危险程度进行分类.实验表明识别正确率达到96%以上.
Common security technology for liquid dangerous goods is unreliable and inefficient.This paper proposes a approach which using characteristics of scattering parameters curve to identify liquid dangerous goods.When centimeter waves penetrate liquids that have different dielectric constants and viscosities,the characteristics of the corresponding scattering parameter curves are different.The instrument uses Ultra-wideband technology to collect a large number of sampling points.These points describe the scattering parameter curve accurately.The perceptron model classifies the liquid by identifying the characteristics of the scattering parameter curve.Experiments show that the recognition rate is over96%.
