Abstract

This paper presents a three-dimensional (3D) interferometric inverse-synthetic-aperture-radar (In-ISAR) image processing for high-frequency electromagnetic scattering prediction of complex targets. The high-frequency electromagnetic scattering is obtained through physical optics (PO) and physical theory of diffraction (PTD). The two-dimensional (2-D) ISAR images are obtained from the frequency-azimuth space data, and the 3-D In-ISAR images are derived from two ISAR images at different incidental altitudes. Results are shown for a three-point simple target and a generic aircraft model
