Matching Pursuits algorithm has been applied to many fields such as data compression,signal feature extraction,time-frequency analysis because of the flexible self-adaptation.The paper first analyzes the usual method of time-frequency spectrum analysis and their defects,then introduces the principle of matching pursuits algorithm.Because the amount of the computation is very huge,genetic algorithm is used to matching pursuits spectrum analysis,which can decrease the amount of the computation effectively.The result of seismic signal MP analysis demonstrates that MP can reveal time-frequency information of the signal effectively.
