Millimeter-wave radar sensors are advanced sensing technologies used across various industries, not tied to a single brand but produced by multiple companies globally. Key manufacturers include Texas Instruments (USA), Infineon Technologies (Germany), and NXP Semiconductors (Netherlands). These sensors operate in the 30–300 GHz frequency range, offering high precision for applications like automotive ADAS (e.g., blind-spot detection), industrial automation (object detection), and smart infrastructure (traffic monitoring). Leading products like TI’s IWR series or Infineon’s BGT60LTR11AIP leverage mmWave for all-weather reliability and millimeter-level accuracy. Industrial suppliers like Radwell and Grainger distribute these sensors for automation, robotics, and predictive maintenance solutions.
