| 摘 要： | 电磁泄漏信号检测已经有好多年的历史,尤其是在电磁兼容学科中,更为重要.然而,电磁信号的不平稳、瞬变、微弱等特点,一直困扰着传统的电磁信号频域检测技术.针对电磁信号频域的这些特点,本文提出了基于小波变换的一种电磁泄漏信号检测技术,并针对实际信号的特点选取了db3作为小波基函数,最后给出了实际检测的结果,以及分析和结论.实际结果表明,该方法可以有效地检测出电磁泄漏信号,为电磁环境检测的智能化作了一个准备.

| Abstract: | The detection of electromagnetic signal leakage has many years of history,especially in the EMC discipline,is more important.However,the electromagnetic signal is not stable, transient and weak.These problems have been bothering us for the traditional frequency do- main electromagnetic signal detection technology.A new electromagnetic signal leakage detec- tion technology based on wavelet transform is presented to solve these problems in this paper. This article selects db3 as the wavelet basis function acc... |
