Design of Integrated Radar-communication Waveform Based on GDS-MIMO-OFDM
The intergrated radar-communication waveform of orthogonal frequency division multi-plexing(OFDM)radar has low communication rate and high autocorrelation sidelobe.To solve these problems,this paper proposes an integrated radar-communication waveform of multiple input multiple output(MIMO)-OFDM based on Gold code spread spectrum.By combining MIMO-OFDM with spread spectrum sequence,the spectrum of communication information is spread by Gold code with good correlation,and then it is modulated with OFDM pulse symbol,thereby an in-tegrated wave is designed which can improve both communication rate and radar performance.The simulation experiment proves that,compared with the Gold-OFDM and pulse compression(PC)-OFDM integrated waveform under the same simulation conditions,the communication rate of the integrated waveform designed in this paper can increase multiple times and the sidelobe of the am-biguity function(AF)of the signal can be reduced without affecting the communication perform-ance,so as to improve the radar performance of the integrated system.
