The Parking Assist System (PAS) application is enabled by Calterah Dubhe 2T4R UWB SoC—CAL1106AQ, the world's first UWB chip to implement the Sensing technology defined by IEEE 802.15.4ab. It delivers centimeter-level height measurement, precise velocity sensing, and stable performances even in harsh weather, while supporting the reuse of digital key car anchors to improve cost efficiency of automotive UWB systems.With a range of technical innovations, Calterah has tackled real-world challenges of deploying UWB PAS radar:
- The Dubhe chip offers an innovative Radar Leakage Suppression (RLS) module and a 2T4R architecture, to solve the challenges of height measurement and hanging object detection;
- The Fine Timing technology and multi-channel advantages ensure concurrent operation of ranging and radar functions, enabling real-time sensing and precise positioning at high vehicle speeds;
- As the world's first to implement the IEEE 802.15.4ab-defined Sensing technology, the UWB chip enables precise multi-anchor synchronization and scheduling, significantly reducing inter-anchor interference. Under the bi-static radar mode, the chip achieves centimeter-level accuracy in static target detection, meeting the stringent requirements of UN Regulation No.158.
From tight parking spots to complex environments, UWB PAS makes parking more precise—empowering smart mobility and worry-free experiences.
