【摘要】 根据地震振幅的衰减特性,提出了一种将希尔伯特变换瞬时振幅特性与函数极值判别法和曲线拟合法应用到地震振幅增益中的方法,称为自适应振幅增益。采用该方法进行的增益结果主要应用于地质构造分析。文章介绍了该方法的相关原理和实现步骤,用模型检验了该方法在振幅增益中的有效性,并且将该方法成功应用于实际地震记录处理中。更多还原

【Abstract】 According to the attenuation characteristic of the seismic wave,we put forward a new amplitude gain method,which applying the instantaneous amplitude characteristic of Hilbert Transform,the distinguishing Method of the function extreme value and the curve fitting method to seismic amplitude gain,is called the self-adaptive amplitude gain.It introduces the relative principles and the realization steps.Its effectiveness in the amplitude gain was proved by the theoretical model,and it was successfully applied to the real seismic record processing.更多还原
