Boston startup Teradar is creating a vehicle sensor capable of detecting objects and pedestrians in adverse weather, with optimal testing conditions provided by over 60 inches of snow this winter. The sensor, effective up to 1,000 feet, has received a $1.9 million contract from the U.S.

Army to enhance situational awareness for military vehicles. Teradar raised $150 million in funding and plans to develop this technology for civilian use, focusing on improving safety. The sensor utilizes terahertz waves, which can penetrate through snow and rain. Teradar aims to make the sensor widely available for all vehicles, with an anticipated cost between current radar and LiDAR systems.
