Abstract:A coherent dual-band microwave photonic (MWP) radar system is proposed and experimentally demonstrated in this paper.In the transmitter, coherent dual band linear frequency modulation (LFM) waves with the characteristics of tunable central frequency and the same large bandwidth are generated based on an improved optical frequency operation module (OFOM).In the receiver, the information of targets is obtained after the echoes at two bands are received and de-chirp processed simultaneously. Experimentally, the p… Show more
