Abstract-”Objects in low earth orbit such as CubeSats and the
International Space Station (ISS) move with constant velocity
along a linear trajectory when viewed from a ground-based radar.
The small change in attitude of the object as it flies overhead
permits the generation of an inverse synthetic aperture radar
(ISAR) image. In this paper, Altair's FEKO software is used to
model the monostatic radar scattering from the ISS as a function
of frequency and aspect angle. The computed data is used for
generating a simulated ISAR image from a ground-based radar.
The system design requirements for the radar are calculated from
the radar equation.
