Improvement of the Resolution Ratio of the Seismic Record by Balanced Biorthogonal Multi-wavelet Transform

This paper discusses an attempt to improve the resolution of a seismic record by using balanced biorthogonal multi-wavelet transform. Wavelet transform offers a lot of local information of seismic signals relevant to time, space, frequency and wave number. Compensation for the loss of high frequency information allows an improvement of the resolution ratio of the seismic record. Numerical results show that the suggested method has several advantages over single wavelet in feasibility and effectiveness and the practice shows some satisfactory results.
