Abstract

High resolution THz inverse synthetic aperture radar (ISAR) imaging for the aircraft is simulated using 0.22THz stepped-frequency (SF) radar system which is designed in the paper. Based on the small rotate angle and the far field approximation, the Range-Doppler algorithm is proposed to reconstruct THz ISAR image of the aircraft. The simulation results indicate that THz stepped-frequency radar can achieve high resolution ISAR images of the aircraft, the resolution of the ISAR images can reach centimeter-scale, which laid a theoretical foundation for radar imaging in THz band.
