A performance enhancement technique for a Joint FMCW RadCom system

The emerging trend of autonomously driving vehicles brings an increasing need for communication. In a setting comprising connected vehicles, information about the environment and vehicles themselves will be shared with other vehicles. Existing communication standards may not be able to meet this growing demand on communication bandwidth. Radar embedded communication can help overcome this bottleneck at the expense of degraded radar performance. In this work we introduce and demonstrate a novel radar signal processing technique to compensate for the self-interference due to the communication content on a chirp modulated radar signal. Recovery of the radar performance is demonstrated by simulations for the continuous phase modulation on the chirp modulation.
