Research on Anti-Electromagnetic Interference Method of Dosimeter Based on Wavelet Transform and PRI Sorting

随着我国核技术应用的发展,日常生活中接触电离辐射的人数也在急速增加,与之对应的检测装置也在不断发展.在剂量仪等检测仪器的研发过程中,如何去除电磁干扰等干扰信号是研究重点,因此本文提出一种基于小波变换与PRI分选的抗电磁干扰方法.使用小波变换对信号进行调制类型识别,基于此再用改进的PRI算法对信号进行分选,选出需要进行处理的信号.实验结果表明,本方法具有良好的效果.

With the development of nuclear technology and applications in China,the number of people exposed to ionizing radiation in daily life is also increasing rapidly,and the corresponding detection devices are also constantly developing.In the research and development process of dosimeters and other detection instruments,how to remove electromagnetic Interference signals such as interference are the focus of research.Therefore,this paper proposes an anti-electromagnetic interference method based on wavelet transform and PRI sorting.The wavelet transform is used to identify the modulation type of the signal.Based on this,the improved PRI algorithm is used to sort the signal.The signal to be processed is selected,and the experimental results show that this method has a good effect.
