摘　　要：用MATLAB对电快速脉肿群干扰试验所用干扰脉冲波形进行了频谱分析。结果表明,这种干扰是一种广谱干扰,用普通的滤波方法很难消除。为此,提出了用吸收式滤波器消除这种干扰的方法以及实现过程中试验、调试应注意事项。A frequency spectral analysis is made on the interferential pulse waveform used in fast electrical pulse train interference by using MATLAB.The result shows that the interference is wide spectral,of which it is hard to be eliminated with a common filtration method.Therefore a method for eliminating the interference with a absorptive filter and precautions for testing and debugging in the implementation are introduced.

关 键 词：快速脉冲群干扰 频谱 吸收式滤波器
