Abstract :
First, the false peak of Burg Spectrum estimation is introduced. In this paper, a new method of eliminating false peak based on Empirical Mode Decomposition is proposed. Secondly, this new method is used in the Line spectrum analysis of ship radiated noise simulation signal. Compared with traditional Linear Spectrum analysis, it is a better method for signal analysis and processing.
