在传统的小波降噪基础上,根据Wiener滤波器和小波变换的特点,采用小波域Wiene滤波器对航空γ能谱谱线数据进行了降噪处理,取得了良好效果。采用该方法对内蒙某地区的航空γ能谱数据进行了处理,结果显示,该方法能有效降低原始能谱数据中统计涨落带来的影响,其降噪效果优于传统的降噪方法。 On the basis of the traditional wavelet denoising, based on the characteristics of Wiener filter and wavelet transform, the Wiene filter in the wavelet domain is used to denoise the data of the aeronautical γ energy spectrum, and the good effect is achieved. The method was used to deal with the airborne γ-ray data in a region of Inner Mongolia. The results show that this method can effectively reduce the impact of statistical fluctuations in the original spectrum data, and its noise reduction effect is better than the traditional noise reduction method.
