【摘要】 基于波动理论,可将地震波场分为入射波场和散射波场。在一定的假设基础上,通过波阻抗差函数可把入射波场和散射波场联系起来。利用波阻抗差函数,可对地震数据中的散射波场进行预测,进而达到去除散射噪声的目的。经正演模型和对实际数据的应用,显示了该方法对衰减近地表散射噪声的优越性。更多还原

【Abstract】 Based on wave theory,seismic field can be divided into incident wave field and scattered wave field. The incident wave field can be related with the scattered wave field through wave impedance difference function on appropriate assumptions. The scattered wave field in seismic data can be forecasted by using wave impedance difference function so as to reach the intention to eliminate scattered noise. Through the forward modeling and application of field data,this method shows the priority on attenuating near--surface scattered noise.更多还原
