The present invention provides a method and system for attenuation of acquisition geometry imprint in seismic data. the method of one embodiment of the present invention includes receiving seismic data (12). The amplitudes of the seismic data are raised to a predetermined power (14). The reciprocal of the raised amplitude data is computed to produce weights (15). A time slice across a CMP gather of the weights is selected (19), and the weights of the time slice are stacked (25). The original input amplitudes are scaled (20) using the weights and stacked (23). The stacked scaled weighted amplitudes are divided by the stacked weights to produce the output amplitudes (27). |
