The inverse problem in radar and optical imaging
Abstract
The reconstruction of a three-dimensional density function from its projections is usually handled by reconstructing a sequence of two-dimensional slices of the object. Certain radar and optical imaging problems require a more direct reconstruction technique. Several 'convolve-and-backproject' solutions are derived for three-dimensional reconstruction from surface projections, parallel-beam ray projections and divergent-beam ray projections. Some practical convolving functions are presented.
