4D radar firm bitsensing, ZETA Mobility, KAIST target automotive

4D imaging radar sensing for automotive applications has taken another step forward with the announcement that three South Korean outfits–bitsensing, ZETA Mobility, and the Autonomous Vehicles and Embedded Systems (AVE) Lab of Korea Advanced Institute of Science and Technology (KAIST)--have signed a Memorandum of Understanding to co-develop “a real-time, embedded AI-based solution that enhances the performance of 4D imaging radar,” the companies stated.

Under the agreement, bitsensing, a company which late last year teamed up with NXP Semiconductors to pursue 4D imaging radar applications, will provide hardware platform while KAIST AVE Lab will contribute AI algorithms based on radar signal processing and sensor fusion, and ZETA Mobility will offer large-scale automotive datasets and embedded AI expertise. Together, the three organizations will collaborate on R&D to accelerate commercialization, the stated.  

Unlike conventional radar, 4D imaging radar captures not only distance, velocity, and direction, but also elevation (Z-axis), enabling highly accurate detection and classification of objects in complex environments. It has been viewed as an increasingly important ADAS autonomous driving component due to its inherent robustness in rain, snow, and fog. Through this collaboration, the partners expect to significantly improve the recognition and classification accuracy of vehicles, pedestrians, and infrastructure on the road, they stated. 

"4D imaging radar is a key sensor for autonomous driving that demands both high precision and all-weather reliability,” said Jae-Eun Lee, CEO of bitsensing, in a statement. “By combining bitsensing’s proprietary radar expertise with the AI and dataset capabilities of KAIST AVE Lab and ZETA Mobility, we are taking a major step forward in bringing next-generation radar solutions to market."  

Professor Seung-Hyun Kong of the AVE Lab at the Cho Chun Shik Graduate School of Mobility at KAIST added, "This agreement is particularly significant as it represents collaboration among institutions that possess core technologies essential for developing artificial intelligence for 4D radar." 

Hyunseok Lee, CEO of ZETA Mobility, stated. “This partnership, through which specialized institutions collaborate to solve technological challenges and develop world-class solutions, is extremely meaningful. ZETA Mobility will leverage our embedded AI expertise to contribute significantly to advancing and commercializing autonomous driving technologies.”  

The three parties will pursue phased cooperation—including joint R&D, performance validation and field testing, and technical advancement—to drive real-world adoption of AI-based 4D imaging radar in the automotive industry.
