The IRS-TMR850 series is a compact, short‑range, high-resolution 4D millimeter-wave radar operating at 80 GHz. Built on TI’ two‑stage cascaded chip architecture, it delivers precise detection of both moving and stationary objects at distances up to 500 meters with the ability to track up to 512 targets simultaneously, outputting distance, velocity, angle data. Seamlessly integrating with video cameras to create a unified radar‑vision fusion system, it also connects with smart traffic lights for adaptive signal timing control that reduces congestion and cuts manual intervention. Built for adaptability, the IRS-TMR850 provides reliable, all‑weather situational awareness that makes roads safer, smarter, and more efficient.
