Teradar reveals its first terahertz-band vision sensor for cars

Two months aft coming retired of stealth with a $150 cardinal raise, Boston-based Teradar is showing disconnected its archetypal flagship terahertz sensor astatine this week’s 2026 Consumer Electronics Show. The institution is positioning the sensor, called Summit, arsenic the archetypal long-range high-resolution sensor of its benignant “designed for precocious show successful immoderate benignant of weather, filling a captious spread near by bequest radar and lidar sensors.”

The sensor volition commencement shipping until 2028 if Teradar tin fastener down contracts with automakers. If that happens, the institution expects the Summit volition assistance alteration those companies to adhd partial, oregon adjacent full, autonomy features to their vehicles.

Teradar’s full attack is astir leveraging the relatively-unused terahertz set of the electromagnetic spectrum betwixt microwaves and infrared. On apical of that, it’s a solid-state sensor, meaning determination are nary moving parts. All this is meant to springiness Teradar’s sensor the champion qualities of lidar and radar sensors, with fewer of the drawbacks.

It’s a perchance charismatic proposition for automakers who mightiness wince astatine the outgo of lidars oregon the limitations of radars, and Teradar says it’s already doing the enactment to beryllium retired its tech. The institution says it has been successful improvement with 5 apical automakers from the U.S. and Europe and 3 Tier 1 suppliers.

Teradar’s impending introduction into the marketplace comes astatine a pivotal infinitesimal for automotive sensor suppliers. Leading U.S. lidar institution Luminar conscionable filed for bankruptcy extortion successful December aft contracts with Volvo and Mercedes-Benz fell apart, as those automakers backed distant from the tech.

Those deals besides crumbled successful portion due to the fact that of low-cost contention from China, according to Luminar. Lidar adoption has been beardown successful China’s car market, and shows small motion of slowing up. In October, Chinese lidar institution Hesai announced it built much than 1 cardinal lidar sensors successful 2025.

Other U.S. companies successful the space, similar Ouster — which acquired and merged with rival Velodyne aft a question of consolidation — person diversified beyond automotive into imaginable markets similar robotics and astute infrastructure.

Teradar is looking beyond automotive, too, and that imaginativeness was reflected successful its caller raise. The $150 cardinal Series B included backing from Lockheed Martin’s task limb and VXI Capital, a new defense-focused fund led by the erstwhile CTO of the U.S. military’s Defense Innovation Unit.

Lidar isn’t wholly dormant successful the car industry. Rivian announced successful December that it volition integrate a roof-mounted lidar sensor (from an unnamed supplier) successful its upcoming R2 SUV, signaling that determination is inactive an appetite to usage precocious sensor exertion to bring autonomy to rider vehicles — particularly if it’s affordable.

Teradar CEO Matt Carey told TechCrunch successful November that helium believes his terahertz sensor tin conscionable each those marks, and sounded anxious to pounce connected the opportunity.

“Our main occupation is to marque definite our sensor gets connected each automobiles, and immoderate the champion mode to bash that is, that’s what we’re going to pursue,” helium said.
