Proprietary millimeter wave (mmWave) radar technologies are widely used in luxury cars to enable active safety functions such as cruise control and collision avoidance. Vehicle-to-vehicle (V2V) communication using the dedicated short range communication (DSRC) technology permits basic low-latency safety applications such as forward collision detection in the 5.9 GHz band. The DSRC technology supports only low data rates, which is not sufficient to handle the gigabytes that can be generated in the next generation vehicles. This challenge can, however, be overcome by using mmWave V2V communication technology that has not been adopted yet by the automotive industry. In this thesis, we propose an IEEE 802.11ad V2V-radar system that leverages the waveform and the typical receiver algorithms of a mmWave consumer WLAN standard to enable a joint framework of vehicular communication and radar technologies at 60 GHz. It will lead to efficient spectrum usage, enhanced performance and increased penetration in the vehicles with minimal size and cost of the hardware. Our theoretical analyses and numerical simulations show promising results; Gbps data rate is achieved simultaneously with cm-level range accuracy, cm/s-level velocity accuracy and high probability of detection at a significantly low false alarm rate.
