TRUE AMPLITUDE RECOVERY FOR PULSE SOURCE SIGN-BIT SEISMIC RECORD WITH PHYSICAL ENVIRONMENT NOISE

The topic coming up for discussion in this paper deals specifically wild the true amplitude recovery (TAR) for pulse source sign-bit seismic record with physical environment noise which is assumed to be the Gaussian distribution. And this does help suit the needs of noise distribution in true amplitude recovery for sign-bit seismic record,so it is unecessary to restack the artificial noise. On condition of the Gaussian noise distribution.no way to perform TAR by using stack only. In this case, correction for the stacked result has to be made. With the attempt to reduce to minimum the stacking fold required for TAR so as to ensure the successful performance of TAR,while making field data acquisition,it's of paramount importance to pick an appropriate layout chart and equally important is to control the charge size so that to confine the dynamic range to be required for signal recovery. In data processing,smoothing filter is still to be required even after correction. Thus,a preferable result of recovery could be expected.
