| Abstract: | The effect of using conventional KL transform to remove strong energy random noises of seismic data is not very good.Based on this method,a new method of removing random noises which combines quadratic wavelet transform and KL transform is proposed.The results show that the new method can improve the effect of disposal and improve signal to noise ratio by processing the synthetic data and real data. |

| Keywords: | seismic data KL transform quadratic wavelet transform random noises |
