开发了一种主动调频连续波（FMCW）太赫兹（THz）系统，用于对毫米级分辨率的物体进行三维成像。二维（2-D）孔径合成可以提高交叉距离分辨率，其高距离分辨率是通过使用频率范围为514 ~ 565 GHz的宽带扫描信号来实现的。通过对解密数据导出的波数域方法，三维数据得到了充分的聚焦。本文介绍了基于合成孔径雷达（SAR）技术的太赫兹三维成像策略、相关理论背景和实验结果。
An active frequency-modulated continuous wave (FMCW) terahertz (THz) system has been developed to image objects in millimeter-scale resolution in three dimensions. The two-dimensional (2-D) aperture synthesis enables the improvement of cross range resolution, and its high range resolution is achieved through the use of the broadband sweep signal, whose frequency ranges from 514 to 565 GHz. The 3-D data are sufficiently focused by the wavenumber domain approach derived for the dechirped data. We present the THz 3-D imaging strategy using synthetic aperture radar (SAR) techniques, the related theoretical background and the experimental results in this paper.
