"Two months after coming out of stealth with a $150 million raise, Boston-based Teradar is showing off its first flagship terahertz sensor at this week's 2026 Consumer Electronics Show. The company is positioning the sensor, called Summit, as the first long-range high-resolution sensor of its kind "designed for high performance in any type of weather, filling a critical gap left by legacy radar and lidar sensors.""
"Teradar's whole approach is about leveraging the relatively-unused terahertz band of the electromagnetic spectrum between microwaves and infrared. On top of that, it's a solid-state sensor, meaning there are no moving parts. All this is meant to give Teradar's sensor the best qualities of lidar and radar sensors, with few of the drawbacks. It's a potentially attractive proposition for automakers who might wince at the cost of lidars or the limitations of radars, and Teradar says it's already doing the work to prove out its tech."
"Teradar's impending entry into the market comes at a pivotal moment for automotive sensor suppliers. Leading U.S. lidar company Luminar just filed for bankruptcy protection in December after contracts with Volvo and Mercedes-Benz fell apart, as those automakers backed away from the tech. Those deals also crumbled in part because of low-cost competition from China, according to Luminar. Lidar adoption has been strong in China's auto market, and shows little sign of slowing up."
Teradar introduced Summit, a solid-state terahertz sensor intended as a long-range, high-resolution automotive sensing solution that performs in all weather. The company plans to begin shipping by 2028 if automaker contracts are secured and expects Summit to support partial or full autonomy features. The sensor leverages the terahertz band between microwaves and infrared and has no moving parts to combine lidar-like resolution with radar-like robustness. Teradar reports development work with five major U.S. and European automakers and three Tier 1 suppliers. Market timing coincides with upheaval among lidar vendors and strong low-cost lidar production growth in China.
