A Novel Frequency Hopping-Aided FMCW Integrated Radar and Communication System

While the frequency-modulated continuous-wave (FMCW) based scheme has been considered as a candidate for realizing integrated radar-communication (RadCom) systems, it still suffers from the low transmission rate. To resolve this issue, we in this paper propose a frequency hopping-aided FMCW RadCom system along with the corresponding radar detection and communication signal demodulation approaches. Our proposed system can significantly improve the transmission rate with only slight degradation of the radar performance. Since the interference could degrade the system performance, we discuss the interference problem and the interference avoidance solution. By simulations, we validate the efficacy of the proposed system.
