Abstract

This paper investigates the expected performance of a ground-based, multi-story building imaging radar system through far-field and near-field computer models. We created a 3-D computer-aided design model of a complex two-story building, simulated the radar response from this complex structure for various geometries and applied synthetic aperture radar image formation algorithms consistent with the simulation scenarios. In this study, we employed the Finite Difference Time Domain method and the Xpatch software to compute the radar signatures. The numerical results give a better understanding of the phenomenology of the scattering and imaging processes and show that relying solely on the far-field scattering data at one elevation angle is not sufficient to obtain the multi-story building layout. Multiple elevation angle views are required in order to determine the location of imaged objects in the vertical direction. Xpatch simulation results in a near-field strip-map configuration suggest a way to achieve this goal within the constraints of a ground-based radar system.
