Abstract:

In this research program we developed novel analytical and computational methods to estimate the support of radiating sources and scatterers from knowledge of the corresponding far field radiation pattern or scattering amplitude. The focus was the development of methods to estimate the so-called minimum source region or scattering support of a far field. The support of any source that generates the given far field must contain this minimum source region. The results were derived in the framework of the Helmholtz equation. The derived methodology consisted of two components, one for the estimation of convex support information, and a subsequent procedure to estimate the nonconvex support. This project also led to new theoretical and computational developments in estimation-theoretic assessment of radar target separation estimability from far field data as well as to a new change detection method called the optical theorem detector, which is relevant to detect unknown targets and changes in random and complex media.
