May 6, 2019 - Vista, California - Axiom Test Equipment, an electronic test equipment rentals and sales company headquartered in North County San Diego, has published a blog post entitled, "Keeping Self-Driving Vehicles on the Road," which discusses the technical and test requirements for the mm-wave radars and optical wavelength Lidar systems used for precise, fast-acting sensing and processing. Sophisticated test equipment is required for development, all of which Axiom Test Equipment can provide on a sale or lease basis.
Self-driving cars, also known as autonomous vehicles, are literally right down the road. These electronically guided vehicles of the future will be built with advanced driver assistance system (ADAS) hardware and software, using several different technologies to detect and track other cars, pedestrians, and objects on the road and steer the vehicle and its driver clear of harm. One of the key technologies in vehicular ADAS electronic systems will be 77-GHz radars.
ADAS uses several sensor technologies, such as optical, laser-based LiDAR, and radar sensors, to provide constant input information to a computer control system for each vehicle. The sensors are mounted in the front and the back of the vehicle for longer-distance monitoring and at the four corners of the vehicle, for more short-distance monitoring. The signals from the sensors are transferred from the sensors to a central vehicle computer via an in-vehicle wireless communications network. The central computer is programmed to control the vehicle to take appropriate action, such as swerve out of the way of a pedestrian in the road. The sensors being used in ADAS equipment assume constant involvement on the part of a driver, although many of these sensors are part of evolving electronic sensor systems which will be part of fully autonomous, self-driving vehicles.
Although many ADAS and autonomous vehicle electronic systems are currently being designed with both 24- and 77-GHz radar sensors for short- and long-range coverage, respectively, eventually radar sensors operating from 77 through 81 GHz will provide the radar coverage for self-driving vehicles. The 24-GHz band is considered a temporary application for short-range radar, to be discontinued as the frequency band becomes even more congested with other applications. The 77-GHz frequency band, however, presents a real, long-term opportunity for millimeter-wave test applications for generating and analyzing radar signals. The 77-GHz radar sensors and systems support several safety systems within each ADAS setup, including adaptive cruise control (ACC), blind-spot detection (BSD), forward-collision-warning (FCW), and rear-collision-protection (RCP) systems ...

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas
and reference material while performing my work as an RF system and circuit design engineer.
The Internet was still largely an unknown entity at the time and not much was available
