High Resolution Radon Transform and its Applications in Multiple Suppression of Seismic Data in Deep-Sea

The multiple reflections develop in deep-sea. Especially in rough deep-sea bottom, the multiple is more complicated. Conventional radon transform filtering has its deficiency, and the effection is not obvious in multiple suppressing of seismic data in deep-sea. In order to achieve high resolution radon transform, this paper proposes an improved method. This method is able to build a very good model of multiple reflections, then suppress the multiples, overcome the deficiency by conventional radon transform. To verify the efficiency of this method, the rough deep seafloor model was established. By using this method, good results were obtained. At the same time, the method has been applied to process many real deep-sea seismic data, the high-precision seismic data profile was gained and obvious effects of application were achieved.
