4D Imaging Millimeter-Wave Radar R7872F – High-Performance Forward Radar with Waveguide Antenna

The R7872F is a next-generation 4D imaging millimeter-wave radar featuring an 8T8R waveguide antenna design, 300 m detection range, and superior angular resolution. Optimized for cost and performance, it is engineered for advanced driver assistance systems (ADAS) and L3/L4 autonomous driving applications.

Detailed Product Description：

The R7872F 4D Imaging Millimeter-Wave Radar is a premium automotive-grade forward radar designed to deliver exceptional perception accuracy in all weather and lighting conditions. Equipped with 8 transmit and 8 receive channels and dual Calterah 844 chipsets, it offers a 300 m maximum detection range and industry-leading 0.8° horizontal resolution with 1.5° vertical resolution.

The radar’s waveguide antenna architecture ensures low-loss, high-gain performance, while its cost-optimized hardware platform meets the rigorous demands of large-scale automotive production. Its robust IP6K9K & IP67-rated housing ensures durability under harsh environmental conditions.

Leveraging cutting-edge 4D point cloud generation, object detection (OD), and advanced interference mitigation algorithms, the R7872F enables precise detection of vehicles, pedestrians, and obstacles—including small, low-height, or partially occluded targets—making it ideal for ADAS and autonomous driving perception stacks.
