This talk discusses the enhancements in radars, LiDARs, GNSS, IMU, Ultrasonics, Microphones and in-cabin sensing necessary for the higher levels of autonomy on consumer vehicles. It focuses on technology trends, performance-cost trade-offs, and regulatory requirements. Specifically, we cover MMIC and signal processing advances on radars that improve angular resolution, range and power consumption. For LiDARs we compare different types of photodetectors, lasers, scanners and wavelengths. Similarly, on GNSS and IMU we evaluate the RF and MEMs requirements and vehicle packaging aspects for their optimal performance. Finally, we explore audio processing on microphones and child presence detection using in-cabin radars.
