| 摘 要： | 针对现有辐射电磁兼容标准测试方法仅能得到辐射总噪声,而无法诊断辐射噪声机理,利用盲源信号分离算法进行辐射噪声源分析与定位,并结合近场波阻抗理论实现辐射噪声机理诊断。理论与实验结果表明,采用文中方法可提取辐射噪声源特性,抑制辐射噪声,并通过GB 9254 Class B标准,从而验证方法的有效性。 |
| 关 键 词： | 电磁兼容 盲源信号分离 辐射噪声 机理诊断 噪声抑制 |

| Abstract: | Since the total radiated noise is obtained by employing the standard electro-magnetic interference(EMI) measurement,and the radiated noise mechanism cannot be diagnosed,a radiated source reconstruction is implemented based on blind source separation(BSS) algorithm.Furthermore,the radiated noise mechanism is analyzed according to the near-field wave impedance measurement.Theorical and experimental results show that radiated source characteristic is extracted.It can meet GB 9254 Class B and has good validity. |
| Keywords: | electromagnetic compatibility blind source separation radiated noise mechanism diagnosis noise reduction |
