Abstract
The shallow geological exploration is more and more widely applied. Scattered wave is a research method of geological exploration which is more close to the real seismic waves, and NMO is one of the key steps in seismic data processing. But conventional NMO method cannot completely give play to the advantages of the scattered wave. Conventional NMO prone to make seismic waves stretch distortion and destroy the original information of seismic wave data, and then, affects the accuracy of seismic data processing results. So this paper proposes a scattered wave NMO method based on adaptive algorithm. This paper analyzes the propagation characteristics of scattered waves, make full use of the adaptive time delay estimation which does not need the statistical properties of the signal and automatically adjust the system parameters to achieve the optimal characteristics, then obtain time delay information. This method able to take full advantage of the characteristics of scattered wave, effective decrease NMO stretching distortion, improve the resolution ratio of seismic data processing results, and effectively retain amplitude and phase information of seismic wave.
