A 0.2 THz stepped frequency radar imaging system with 12 GHz bandwidth which uses inverse synthetic aperture to realize two-dimensional high resolution imagery is proposed and designed. The results of Matlab simulation based on system design parameters show that the THz radar imaging system could realize two-dimensional high resolution imagery of the target, and the horizontal and vertical distance can reach centimeter-level resolution.
