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.
