中心硕士生刘运坤的工作——Photonic ADC-based scheme for joint wireless communication and radar by adopting a broadband OFDM shared signal（实现采用宽带OFDM一体化信号来验证基于PADC的雷达通信一体化方案）的相关成果近期被Optics Letters期刊接收发表，该工作得到了国家重点研发计划（2019YFB2203700）、国家自然科学基金（T2225023）的部分资助。我们提出了一种基于PADC的雷达通信一体化方案。该方案能够实现对大带宽射频信号的接收采样。因为OFDM信号在通信应用中具有显著优势，我们采用OFDM一体化信号来验证所提出的方案，通过一体化信号同时实现高速通信和高性能目标探测。在实验中，通信速率达到了6 Gbit/s；ISAR成像的分辨率为3.97 cm × 2.94 cm。并且进一步验证了在通过调整脉冲重复周期进行更远距离目标（约374.6 m）的探测时，该系统仍能保持高精度距离分辨率和高速通信。因此，我们预计这项工作将发挥微波光子技术的优势，为实现具有大带宽信号处理能力的雷达通信一体化系统提供一种可行性方案。
摘要:We propose and demonstrate a novel joint wireless communication and radar system based on a photonic analog-to-digital converter (PADC), which can receive broadband radio-frequency (RF) signals. Owing to this property, a broadband orthogonal frequency division multiplexing (OFDM) shared signal, which owns obvious advantages in communication applications, can be adopted to realize efficient data communication and high-performance target detection simultaneously. In the experiment, the communication rate of 6 Gbit/s is achieved. Inverse synthetic aperture radar (ISAR) imaging is demonstrated with a two-dimension (2D) resolution of 3.97 cm × 2.94 cm. Finally, it is verified that high accuracy radial resolution and high-speed communication can be maintained while increasing the pulse repetition period to detect remote target at around 374.6 m.
