This work presents a novel joint communication and sensing (JCAS) system that uses code spread spectrum (CSS) techniques to generate a signal for simultaneous communication and sensing. The transmission signal and the signal processing in the radar receiver must be adapted to achieve a high dynamic range so that the radar performance does not suffer. A compromise between bit rate and dynamic range must be found. Measurements verify the performance in a physical JCAS system. A dynamic range of 55 dB and a bit error rate (BER) of 2.10−3could be achieved with a maximum length sequence (m-sequence) of length 511.
