Sensing Performance of Wideband Full-Duplex Joint Radar-Communications FM-FSK Transceiver

We study through simulations a system of two full-duplex integrated sensing-and-communications transceivers, which embed data onto a frequency-modulated (FM) continuous-wave radar signal through frequency-shift keying (FSK). Each processing receiver has to extract both target and data information while being subject to self- and mutual interference, including radar echoes. We evaluate sensing and communications performance of this setup under ideal conditions as well as under imperfect synchronization, with the focus on sensing. Under these conditions the setup is estimated to be capable of, e.g., detecting a 1 m

radar target at 8 km while transferring data at 400 kbit/s.
