基于Kjartansson模型的反Q滤波

利用Ｋｊａｒｔａｎｓｓｏｎ提出的数学模型，建立包含有衰减和频散的正演模型。从这个模型出发，推导出适合于处理非平稳地震记录的反Ｑ滤波。用该方法不仅能补偿振幅的衰减，而且还能消除频散。通过对实际资料的处理，其结果是令人满意的。最后，给出了在最佳意义下的反Ｑ滤波方法。

INVERSE Q FILTERING ACCORDING TO KJARTANSSON MODEL

This paper utilizes the mathematic model that presented by kjartansson to build the forward model including attenuation and dispersion. From the model, wc derived the inverse Q filtering formulation, suitable for processing non-stationary seismic record. This method not only could be adapted to compensate the attenuation of amplitude but also to remove dispersion. We used the formulation of the inverse Q filtering to read profile, the result is satisfied. At last, we presented the technique of the inverse Q filtering under optimum sense.
