Teradar Reveals its First Terahertz-Band Vision Sensor For Cars
Terahertz Car Sensor Breaks Weather Barrier What if self-driving cars could “see” clearly through snow, fog, or heavy rain? That long-standing challenge may finally have a solution. At CES 2026, Boston-based startup Teradar unveiled Summit—the world’s first terahertz-band vision sensor designed specifically for automotive autonomy. Unlike traditional lidar and radar systems, which struggle in adverse weather, Teradar claims its solid-state sensor delivers high-resolution, long-range detection regardless of conditions. If automakers sign on, vehicles equipped with Summit could hit roads as early as 2028. Credit: Teradar The Weather Problem That’s Haunted Autonomy For years, the Achilles’ heel of advanced driver-assistance systems (ADAS) and autonomous driving has been environmental interference. Lidar—once hailed as the “eyes” of self-driving cars—falters in fog, snow, or even dust. Radar, while weather-resistant, lacks the resolution to identify small or distant objects with precision. Th…
