外文摘要：This paper reports a photonics-assisted millimeter-wave[mm-wave]joint radar jamming and secure communication sys-tem constructed through a photonic upconversion technique.In the experiments,a 30 GHz constant envelope linear frequency-modulated orthogonal frequency division modulation[CE-LFM-OFDM]signal with an instantaneous bandwidth of 1 GHz is synthesized by encoding 1 GBaud encrypted 16-quadrature amplitude modulation[16-QAM]OFDM signal.The velocity deception jamming is achieved with a spurious suppression ratio over 30 dB.Furthermore,we efficiently execute range deception jamming with a time shift of 10 ns.Simultaneously,the encrypted 16-QAM OFDM signal is successfully transmitted over a 1.2 m wireless link,with a data rate of 4 Gbit/s.
