Abstract:Three methods for estimating the signal jnoise ratio of seismic data are recommended here,which are stack method,time-domain SVD method and frequency domain SVD method(SVD:singular-value decomposition).The stack method can beused to estimate the signal jnoise ratio of seismic data when the seismic signals of all traces have the same waveform,phase and amplitude.Time-domain SVD method may be taken when the seismic signals on different traces only show amplitude change.Frequency-domain SVD method should be adopted when seismic signals on different traces exhibit both amplitude and phase variations.Theoretical and real dato processing results prove that the methods and their application environments are reasonable.
