摘要：
Traditional terahertz (THz) imaging systems based on scanning mechanism is inefficient, which greatly limits the application of industrial scenarios. To accelerate data collection and achieve real-time imaging, an all-electronic THz imaging system based sparse multiple-input multiple-output (MIMO) array has been developed to achieve target imaging in millimeter-scale resolution. The sweep bandwidth of the system ranges from 220GHz to 325GHz, which guarantees the range resolution. A wide array is designed for realizing high cross-range imaging resolution. The THz images are reconstructed by the backprojection algorithm after the multi-channel error calibration. Finally, the experimental results verify the imaging resolution of the system.
