Autonomous Vehicle Technology: Metawave innovates with analog radar platform

Autonomous Vehicle Technology announces 2020 ACES Award Winner in Autonomy | Sensors category

Metawave Corp.’s product developers believe that many of the safety requirements, as well as expectations for a smooth riding experience, facing the auto industry cannot be met using only today’s sensors, including current state-of-the-art DBF (digital beam-forming) or MIMO (multiple-input multiple-output) radars. They say that leading automakers need an innovative radar that provides longer range, high resolution, greater angular accuracy, and object classification. To deliver the radar of the future, today, the company has developed a state-of-the-art analog platform called Spektra, which it believes is unparalleled in its ability to be modified to fit any automotive sensor suite. The radar uses analog beam-forming and -steering with advanced digital signal processing techniques to deliver a low-cost solution driven by the need for driver assist and automated driving system deployments such as left-turn assist, blind-spot monitoring, automatic emergency braking, adaptive cruise control, traffic jam pilot, and highway pilot. The radar platform is said to identify and classify objects at long range with a higher resolution than today’s radar, with groundbreaking beam-steering capabilities that can enable detection and classification of vehicles beyond 350 m (1150 ft) and pedestrians beyond 200 m (660 ft). Object detection and classification at these ranges is essential for safe, automated driving features. The radar can penetrate difficult weather conditions like dense fog, sand storms, and heavy rain while maintaining high performance. Additional capabilities include the handling of scenarios like the Euro NCAP cut-in and cut-out as well as discerning obstacles in the ego (host) lane from adjacent lanes and distances beyond 300 m (980 ft). As automated driving system development continues to evolve, company product developers are expected to increase range and overcome difficult challenges like a motorcycle parked in the shadow of a bridge during a rainstorm.
