Abstract

Using full-wave computational electromagnetics data, we demonstrate that the radiated field from an antenna on a complex platform can be sparsely represented by a radiation center model. An extraction scheme based on the matching-pursuit algorithm is devised to extract the model parameters from multifrequeny, multiaspect radiation data. To accelerate the parameterization procedure, the previously developed antenna synthetic aperture radar imaging algorithm is used to provide an initial estimate of the radiation center position during the search. It is shown that the resulting radiation centermodel provides a sparse, physical representatian of the antenna-platform interaction. (C) 2000 John Wiley & Sons, Inc.
