Radar is the only sensor that can realize target imaging at all time and all weather, which would be a key technical enabler for future intelligent society. Poor resolution and large size are the two critical issues for radar to gain ground in civil applications. Conventional electronic radars are difficult to address due to both issues, especially in the Ka band or lower. In this work, a chip‐based...
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...
