摘要
回顾了地震波散射的概念、研究历史及分类.对散射理论及应用研究成果进行了系统评述,特别对前人关于散射波数值模拟和应用研究的不足进行了总结:(1)观测系统设计不合理;(2)对散射波的特征研究缺乏系统性;(3)对复杂散射波场的识别方法没有进行系统研究;(4)适合散射成像的处理软件还有待开发.并介绍了作者关于地震散射波场特征数值模拟研究的初步成果.
In this paper, the definitions, study history and classification of seismic wave scattering were reviewed at first. Then the research work on scattering theory and its applications were systematically summed up. Especially the deficiencies of the research work in scattered wave numerical simulation and its applications were summed up:①geometry is unseemliness;②lack of study systematically in the scattered wave field characteristic;③lack of study systematically in the scattered wave field recognize and its interpretation;④lack of the program for scattering image. Finally the initial research works of scattered wave field characteristics based on numerical simulation by authors were introduced.
