Abstract :
POCS (projection onto convex sets) is one signal restoration technique by which a priori information can be added easily. In this paper, it is first applied in the recovery of acoustic impedance from seismograms of which low and high frequency components are missing. The experimental results of synthetic and real data show that the new method is more suitable for solving the problem of seismic data processing than previous methods
