Integrated radar and communication system based on stepped frequency continuous waveform
2015
In this paper, a new system of integrated radar and communication which bases on stepped frequency continuous waveform is put forward. Specifically, firstly, the binary communication data are modulated into stepped frequency continuous waveform through BPSK modulation, which can make the communication data hide in the radar waveform. Secondly, we provide a signal separate method which can divide the radar signal and communication signal in the baseband mixed signal. So this integrated system can transmit binary data precisely with little influence on the radar sensing performance. Finally, we evaluate the radar sensing performance and wireless communication performance via simulation results. The results show that the proposed integrated system has a lower SER meanwhile guaranteeing the radar sensing performance.
