Teradar, a Boston-based tech startup, has debuted what it claims is the world’s first terahertz-band vision sensor designed for cars, trucks, and autonomous systems, showcasing the product at the Consumer Electronics Show (CES) 2026 in Las Vegas. The sensor, dubbed Summit, operates in the previously underutilized terahertz portion of the electromagnetic spectrum between radar and lidar, promising both high-resolution object detection and reliable performance in adverse weather conditions where legacy technologies often falter. Teradar, which recently raised $150 million in funding, says the Summit sensor combines the best traits of radar and lidar while overcoming their individual shortcomings, and is already in development partnerships with multiple top-tier automotive manufacturers and suppliers. The company aims to begin high-volume production by 2028, potentially enabling advanced driver-assistance systems (ADAS) or even higher levels of vehicle autonomy. Industry observers note that this innovation arrives as some traditional lidar makers struggle financially, opening a strategic opportunity for terahertz technology to capture market share in next-generation safety systems.

Key Takeaways
• Teradar’s Summit terahertz sensor promises superior all-weather performance and high resolution relative to traditional radar and lidar systems.
• The sensor technology could accelerate the adoption of advanced driver-assistance and autonomous driving capabilities starting as early as 2028.
• The launch comes amid consolidation and financial challenges among established lidar providers, offering a competitive opening for new sensing technologies.
In-Depth
At the 2026 Consumer Electronics Show in Las Vegas, Teradar introduced a cutting-edge automotive sensing platform that may reshape how vehicles understand their surroundings. The terahertz-band vision sensor, branded as Summit, taps into a portion of the electromagnetic spectrum that sits between radar and lidar frequencies, offering a unique blend of range, resolution, and environmental resilience. Unlike conventional radar, which can struggle with fine object discrimination, or lidar, which can be compromised by rain, snow, or fog, terahertz frequencies can provide both high definition and reliable penetration through adverse conditions. That combination is precisely what automakers are seeking as they scale up advanced driver-assistance systems (ADAS) and explore higher levels of autonomy.
Teradar’s recent $150 million funding round underpins its rapid move from stealth to showcase, and the company reports active development collaborations with several major automotive OEMs and Tier-1 suppliers. While pricing and production details remain to be finalized, the plan is for Summit to enter high-volume vehicle programs by 2028, potentially enabling features such as enhanced collision avoidance and automated driving in limited contexts. This timing is crucial because traditional lidar makers have faced headwinds; some have filed for bankruptcy or narrowed focus, underscoring the competitive gap new technologies can exploit. Should terahertz sensors deliver on their promise, they could accelerate safer roadways and strengthen U.S. leadership in automotive tech innovation.
