Abstract

In many practical situations data gathered by sensor arrays are related to a desired image via the Fourier transform relation. In certain problems (such as computer-aided tomography and synthetic-aperture radar) the Fourier domain is sampled over an irregularly shaped support region, and the image must be reconstructed from this partial data set by an inverse FFT operation. The authors consider the problem of designing optimal two-dimensional windows for data regions with irregularly shaped supports. An optimal design strategy is presented and a computer-based algorithm is discussed which iterates between the spatial and frequency domains in order to obtain the best solution which satisfies constraints in both domains.
