Abstract

The Gerchberg algorithm has been successfully applied to signal enhancement, reconstruction and extrapolation problems where only partial information is available in the space (time) and frequency domains. In this paper, the Gerchberg algorithm is applied to the iterative interpolation of two-dimensional (2-D) surfaces from irregularly spaced data points. Specific applications presented are: the generation of hydrographic surfaces from bathymetric data obtained from the hydrographic airborne laser sounder (HALS) and the generalization of wind-flows from cloud imagery obtained from the Geostationary Operational Environmental Satellite (GOES). Experimental results obtained using a VAX 11/780 and FPS 120-B array processor system are presented.© (1983) COPYRIGHT SPIE--The International Society for Optical Engineering.
