Terahertz (THz) technology is increasingly being
used in a wide range of applications, and terahertz radar systems have also
been developed in radar applications. In this paper, the terahertz radar system
is used for 2 dimensional (2D) realtime imaging in near-field scenario within
20m. A real-time imaging system of 170GHz Synthetic Aperture Radar (SAR) is
designed, and the system is simulated and verified by Doppler Beam Sharpening
(DBS) algorithm. The simulation results show that the system can utilize
uniform linear motion to synthesize a short aperture in the near-field range
and form 2D image of scattering points in the scene. The imaging effect is good.
