To address the increasing communication demand driven by envisioned large-scale connected vehicle deployments, the dual use of the 76–81 GHz automotive radar frequency band for joint automotive radar and communication (JARC) system has gained significant interest given the wide and dedicated bandwidth. In this paper, we propose and evaluate a multi-range joint automotive radar and communication system based on pilot-based OFDM waveform. The proposed JARC system exploits the dynamic allocation of pilot subcarriers to switch between radar specifications for different ranges, e.g. short-range radar (SRR), mid-range radar (MRR) and long-range radar (LRR), to minimize the age of information of the covered regions, while dynamically adjusting the communication data rate based on traffic load.
