Being advantageous to pattern-enhancement and noise-suppression,wavelet transform is applied to extract the frequency band of fibril and zebrapat ternfine structure and remove noise to get their clear characteristics.Then,a pattern recognition algorithm is presented to determine all fine structures in the whole burst regime.Finally the parameters of fine structures is calculated and analyzed so as to understand the physics of solar radio burst .
Key words： solar radio burst; fine structure; wavelet transform
