Conventional parabolic radon transform method cannot attenuate the multiples ideally and causes spatial alias for the short spread and sparse sampling seismic data. After analyzing the papers by Sacchi, Mauricio, Todd Mojesky and some other researchers. on multiples attenuation by using parabolic radon transform method, this paper describes the theory of high resolution parabolic radon transform method. The result shows that the high resolution parabolic radon transform method can efficiently and effectively realize spatial anti-alias multiples suppression after the new method is applied to the model data and real seismic data respectively; meanwhile, this method can overcome the limitation of insufficient samples and short offset.
