FAST IMAGING AND SCATTERING CENTER MODEL EXTRACTION WITH FULL-WAVE COMPUTATIONAL ELECTROMAGNETICS FORMULATIONS

By R. Bunger

Abstract:
The so-called ``fast imaging and scattering centers approach'' originally proposed by Bhalla & Ling has revolutionized the generation of inverse synthetic aperture radar (ISAR) images and scattering center models using computational electromagnetics. Until now this approach has been used exclusively with ray-based methods. The main contribution of this paper is an extension of the Bhalla & Ling formulation for the generation of ISAR images and scattering center models with full-wave methods. Moreover, we discuss an approach to reduce the sampling requirements of the original Bhalla & Ling formulation, rendering the formulation applicable to 3-D imaging of real targets.
