| 摘 要： | 在航空放射性数据处理过程中引入小波分析技术,可得到较传统数据处理方法更为真实、理想的谱数据。研究结果表明:处理后的谱数据能准确识别主能量窗以外的航空放射性谱数据中所包含的微弱信息,从而获得有关研究对象的更多信息;在航空放射性环境测量中,能够正确有效地提取谱数据中低能谱的信息,提高对人工放射性核素的分辨能力。

| Abstract: | The authors applied wavelet analysis to the data processing in airborne radioactive survey, and analyzed the effect of wavelet used in spectral data processing. It is shown that the method of wavelet analysis for spectral data processing can gain more true and more ideal information than the traditional data processing method, and can accurately identify information which is beyond the main energy windows. Thus, the weak information included in airborne radioactive data can be obtained, and the geologists can get more information of the studied objects. The resolution of man-made radioactive nuclides can be improved by using low-energy spectral information in the airborne radioactive survey. |
