摘要:
对辐射干扰噪声产生的机理进行了较为全面的分析研究,设计了一种辐射电磁干扰的近场测试方案和辐射干扰源,并针对辐射电磁干扰近场测试精度低的问题,提出了一种基于方差分析的多项式拟合校准算法,以3 m法暗室测试结果为校准算法的基准.并采用matlab进行了算法处理,对校准精度进行了实验验证,结果表明:经过校准算法处理,近场测试结果能够与3 m法暗室测试结果基本吻合,验证了该校准方法的有效性.
Abstract:
In this paper， the mechanism of radiated interference noise is comprehensively analyzed，and both an radiated EMI near-field test method and a kind of radiated interference source are designed． For the low accuracy of radiated EMI near-field test，a polynomial fitting calibration algorithm based on variance is proposed，and the result of 3 m chamber is the baseline of the calibration． In addition，the algorithm processing is carried out by using of matlab，and the calibration accuracy is verified by an experiment． The experiment result shows that the near-field test result can be consistent with 3 m chamber test result after calibration，and proves that the calibration method is effective．
