摘要：
A novel terahertz (THz) three-dimensional (3D) imaging scheme based on the multi-circular synthetic aperture is studied in this paper. The integral sidelobe ratio and the imaging resolution is discussed as a function of the signal bandwidth, the number of circular path. The simulated point spread function demonstrates the 3D imaging capability of the novel imaging scheme. The multi-circular synthetic aperture based on array technique can significantly improve the imaging performance.
