In article number 1900239 by Shilong Pan and co‐workers, a chip‐based microwave‐photonic radar is proposed and experimentally demonstrated. Key optical devices in the radar transceiver are integrated on a single chip, which generates a flat linear frequency‐modulated signal occupying the full Ku band (12–18 GHz) and performs wideband de‐chirp processing of the radar echoes. Inverse synthetic aperture radar imaging with a range resolution of 2.7 cm is implemented. This work paves the way for applying microwave‐photonic radars to miniaturized platforms such as UAVs and autonomous vehicles.

微波光子雷达：用于高分辨率成像的基于芯片的微波光子雷达（Laser Photonics Rev. 14（10）/ 2020）

在石龙潘及其同事的文章1900239中，提出并通过实验演示了基于芯片的微波光子雷达。雷达收发器中的关键光学设备集成在单个芯片上，该芯片会生成一个占据整个Ku频段（12–18 GHz）的平坦线性调频信号，并对雷达回波执行宽带去线性调频处理。实现了2.7 cm范围分辨率的逆合成孔径雷达成像。这项工作为将微波光子雷达应用于微型平台（例如无人机和自动驾驶汽车）铺平了道路。
