A field trial of microwave photonic radar system based on photonic arbitrary waveform generator

We demonstrated a photonics-based X-band radar system, in which the transmitter generates a linear frequency modulated signal centered at 10GHz with 2GHz bandwidth based on photonic arbitrary waveform generator (PAWG), and the receiver is based on photonic de-chirping. We conducted a field experiment on this radar system and achieved inverse synthetic aperture radar (ISAR) imaging of non-cooperative targets (airplane), verified the possibility of its application in future radar applications.
