Fully Coherent S- and X-Band Photonics-Aided Radar System Demonstration

A fully coherent dual band radar system based on a single photonic-assisted transceiver is presented. Photonic technologies have been used for simultaneous generation and detection of radar signals in the S- and X-band. The sharing of a single transceiver for both the frequency bands allows for a perfect coherence among the generated waveforms. The system has been tested in an operative aerial scenario, and the presented target detections demonstrate the effectiveness of the proposed architecture.
