讨论了利用Radon变换的一种变体进行多重抑制。这种变换与经典Radon变换的不同之处在于积分曲面是双曲的而不是平面的。这种特殊的双曲曲面在计算费用方面相当于抛物线，但更准确地区分多次反射和初级反射。正演变换通过地震到达点的走时位移差异来分离它们。倍数可以通过仅对部分数据进行反变换来抑制。算例表明，叠前和叠后的地震记录都能有效地衰减倍数。
Multiple suppression using a variant of the Radon transform is discussed. This transform differs from the classical Radon transform in that the integration surfaces are hyperbolic rather than planar. This specific hyperbolic surface is equivalent to parabolae in terms of computational expense but more accurately distinguishes multiples from primary reflections. The forward transform separates seismic arrivals by their differences in traveltime moveout. Multiples can be suppressed by an inverse transform of only part of the data. Examples show that multiples are effectively attenuated in prestack and stacked seismograms.
