ISAR Simulations of Complex Objects and Verification with Measurements at TUBITAK MRC

Abstract

In this paper, TSAR images of a scaled model target have been demonstrated for the simulated and measurement data at TUBITAK-MRC facilities. The simulation was carried out with a high frequency electromagnetic simulator that can predict electromagnetic scattering from large and complex bodies. The measurement radar cross section data were collected by an TSAR experimental setup with 100 GHz anechoic chamber. All measurements have been supplied by sub-THz vector network analyzer. The millimeter (mm) wave band set-up used for TSAR test-case is presented. For validation, the scaled model of an airplane target has been selected. The two-dimensional ISAR measurements have been performed around the center frequency of 90 GHz. The comparison of the simulated TSAR image of the CAD model of the target and the measured TSAR image of the scaled model provides a good match.
