• Abstract:In this paper, we proposed a tunable K/W-band OFDM integrated radar and com-munication system based on Optoelectronic Oscillator (OEO) for intelligent transportation. All-optical signal processing including amplitude asymmetric filtering and quadratic phase manipulating is applied in OEO to achieve a high-frequency and tunable self-excited oscillation, which supports the K/W-band OFDM signal generation. Its product of maximum detection range and communication capacity is cB/4 increment f (mmiddotGbaud), where c is light speed and increment f is subcarrier spacing of OFDM. A proof-of-concept experiment is carried out in K-band with bandwidth B= 2 GHz and W-band with bandwidth B= 10 GHz. The range resolution increment R, detection range Rmax and communication capacity C of 0.075 m, 75 m, 12.8 Gbps, and 0.015 m, 300 m, 32 Gbps are experimentally demonstrated in K/W-band respectively.(c) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
