The importance of Radon's projection reconstruction theory in radar target imaging
Abstract
In the inverse scattering problem for perfectly conducting objects, the reconstruction of the size and shape of a convex body from its radar cross-sectional areas has been formulated as a Radon problem of image reconstruction from projections. In this paper, the reconstruction from projections problem and its relation with the target reconstruction problem is discussed. By using concepts of Radon's theories and the properties of Ludwig's theorem on supports, the mathematical aspects of reconstruction from projections is examined, and the sparse data problem is analyzed. The limited aperture problem is solved via the Radon transform approach.
