P146 Signal Reconstruction from Incomplete and Misplaced Reasurements S.S. Challa* (University of British Columbia) G. Hennenfent (University of British Columbia) & F.J. Herrmann (University of British Columbia) SUMMARY Constrained by practical and economical considerations one often uses seismic data with missing traces. The use of such data results in image artifacts and poor spatial resolution. Sometimes due to practical limitations measurements may be available on a perturbed grid instead of on the designated grid. Due to algorithmic requirements when such measurements are viewed as those on the designated grid the recovery procedures may result in additional artifacts. This paper interpolates
