舰船噪声包络谱分析
Analysis of the Envelop Spectrum of Navy Vessel’s Noise
【摘要】 用希尔伯特变换求舰船噪声信号的包络谱 ,通过对实测舰船信号的分析 ,讨论了舰船信号包络谱和功率谱之间的关系。
【Abstract】 With Hilbert transform, the envelop spectrum of navy vessel’s noise signals was obtained. The relationship between enve lop and power spectrum is also discussed in the paper.
