Title: Synthetic aperture imaging of dispersive targets


A dispersive target is one whose scattering properties depend on the frequency of the wave incident on it. By reviewing the elementary theory of scattering by a particle, we introduce a dispersive point target model. We then develop an imaging method to identify and approximately locate dispersive point targets with synthetic aperture radar measurements. Using the predicted target locations, we introduce a method to recover information about their frequency dependence. This method opens up opportunities for classifying targets in addition to identifying and locating them.
