INTEGRATED RADAR AND COMMUNICATION SYSTEMS FOR HIGHLY AUTOMATED VEHICLES

The application of radar has spread to numerous civilian automotive purposes like adaptive cruise control, automotive emergency braking, blind spot detection, lane change assist, and so on. The need for ever-increasing rates in wireless communications has moved the frequency spectrum toward millimeter range, usually assigned to automotive radar. This has led to an integrated automotive radar and communication system, which results in limited electromagnetic pollution and lower cost, size, weight, and power. Improved massive multiple input, multiple output signal processing techniques are required as integration of these two systems will be based on large antenna arrays. Similar to the see-through technique of 3GPP Release 16, the authors have conducted a simulation experiment where data of multiple targets have been obtained with automotive radar and then sent to a gateway. From there, data are transmitted to a fifth-generation communication model. Final data obtained at a receiver of the communication system matches the original radar output, which proves that data have been successfully transferred from the radar system to the communication system, thus making it an integrated system. This system is very useful in the case of vehicle platooning. © 2023 by Begell House, Inc.
