Abstract: Due to the alleviated spectral congestion through spectrum sharing, integrating radar and communication has raised increasing attention in both academic and industrial fields. This paper proposes several orthogonal frequency division multiplexing (OFDM) based waveform design approaches for joint cooperation of radar sensing and communication transmission. A mathematical model of comprehensive weight selection, communication modulation mode and phase coding sequence is proposed, aiming at the problems of high peak sidelobe and large envelope fluctuation in OFDM integrated waveform, two feasible schemes to achieve superior performance in terms of ambiguity function are investigated, including the iterative optimization of the peak sidelobe ratio (PSLR) and peak to average power ratio (PAPR) optimization method based on random phase coding, which can improve the range resolution without degrading Doppler resolution. Simulation results show that the proposed waveform optimization method can improve PSLR below −30dB and PAPR below 2, verifying the effectiveness of the designed integrated waveform in simultaneous radar and communication operations.
