Joint communication and sensing (JCAS) combines radar and data transmission into one system. Applying this, a frequency modulated continuous wave (FMCW) radar is chosen for sensing and gets modulated by frequency shift keying (FSK) to transmit data. The transmission takes place at 60 GHz with a bandwidth of 5 GHz which leads to a high sensing resolution of 0.03 m. For comparison, the FMCW radar is evaluated without modulation, with an additional frequency offset and with FSK. The results show that FMCW radar with an additional frequency offset does not substantially impact the sensing functionality. The received FSK data were demodulated and could be reconstructed completely at a measuring distance of 1.9 m and with a bit error rate of 3.6 % at a measuring distance of 2.5 m. A JCAS system in V-band was developed and its functionality proven.
