摘要：We propose and demonstrate a high-resolution single-antenna 3D microwave imaging scheme. Combining the spatial decoupling capabilities of Hadamard modulation, and the broadband characteristics of optical receivers, our scheme can achieve high-resolution 3D imaging resolution with one receiving antenna without scanning. It is experimentally demonstrated that an unmanned aerial vehicle-shaped target can be successfully imaged in 3D. According to the measurement, the resolution of the 3D image can obtain a resolution of better than 4 cm in all three dimensions. We believe that our method will greatly promote the application of high-resolution microwave 3D imaging in complex and changing scenarios with limited equipment.
