车载伽玛能谱测量数据的小波降噪方法分析

Wavelet method for reducing statistical noise in car gamma-ray spectral data

介绍了车载伽玛能谱测量和小波降噪方法,采用MATLAB语言编写了小波降噪程序,并对2006~2007年车载伽玛能谱野外测量数据进行了小波降噪处理,结果表明采用小波分析降低车载伽玛能谱测量数据统计噪声是有效的。

This paper introduces a method of wavelet to reduce noise in car gamma-ray spectral survey.A programe has been developed with MATLAB,which has been used to process the car gamma-ray spectral survey data cellected in 2006—2007.The processed result has validated the method.
