Abstract

We develop robust algorithms (such as ‘matching pursuit’, ‘orthogonal matching pursuit’ which are methods of computing adaptive signal representations with respect to a nonorthogonal dictionary of basic building blocks) in order to decompose thercl signal of a 2D scatterer (an infinite perfectly conducting cylinder of triangular section) as a combination of elementary atoms from a redundant dictionary. Such a decomposition theoretically provides some antenna pattern arrangements that could be used for the minimization of thisrcl.
