A21 3-D FILTER DESIGN ON A HEXAGONAL GRID FOR POINT-RECEIVER LAND ACQUISITION 1 Abstract: Recording seismic data through point receivers rather than analogue receiver arrays has several potential advantages. Design of optimal 3-D digital filters is important to realize this potential. Hexagonal (staggered) spatial sampling is more efficient than rectangular sampling for seismic signals but requires development of special techniques for the design of 3-D filters. We present a method based on the APOCS (Alternating Projections onto Convex Sets) approach for designing optimal 3-D FIR (finite impulse response) filters for digital group-forming. Introduction: Recording seismic data through point receivers rather
