Calterah has introduced two new automotive millimeter-wave (mmWave) radar system-on-chips (SoCs) aimed at advanced driver-assistance systems (ADAS), alongside new ultra-wideband (UWB) radar solutions designed for child presence detection and parking assistance.
The launches were announced during the company’s annual Calterah Day event as automakers and suppliers prepare for increasingly stringent vehicle safety requirements, including upcoming Euro NCAP protocols and proposed Chinese regulations covering Level 2 ADAS and automatic emergency braking (AEB) systems.
The Shanghai-based semiconductor company said the new products are intended to improve vehicle perception capabilities, support higher levels of driving automation, and enhance in-cabin safety applications.
New Radar Chips Target Long-Range Detection
Calterah introduced two new radar SoCs, Kunlun-Pro and Andes-Pro, which are designed to deliver greater detection performance and higher-resolution environmental sensing.
The company describes Andes-Pro as the world’s first 6-transmit, 6-receive (6T6R) ADAS radar SoC. According to Calterah, the chip can detect weak targets at distances of up to 200 meters while providing angular resolution of one degree in azimuth and three degrees in elevation.
Calterah said the platform offers a lower-cost alternative to more complex 8T8R radar architectures while also supporting scalability through a cascaded 12T12R imaging radar configuration.
The second product, Kunlun-Pro, utilizes a 5-transmit, 4-receive (5T4R) architecture. Compared with conventional 4T4R radar solutions, the company claims the chip delivers more than 2.5 decibels of additional signal-to-noise ratio (SNR), 25% more virtual channels, significantly higher computing performance, and improved memory capacity.
According to Calterah, these enhancements enable more reliable tracking of weak targets at longer distances and in challenging operating environments.
Expanding Beyond ADAS with UWB Radar
In addition to the automotive radar chips, Calterah unveiled new UWB radar solutions built around its CAL1106AQ UWB SoC.
The company said the chip is compliant with the IEEE 802.15.4ab sensing standard and certified under the FiRa 4.0 specification. Calterah describes the product as the first UWB SoC to combine both standards while utilizing a 2-transmit, 4-receive architecture.
Two development platforms based on the chip were introduced:
- A Child Presence Detection (CPD) suite designed to monitor vehicle interiors and detect occupants.
- A Parking Assist System (PAS) suite intended to support parking and low-speed maneuvering functions.
Calterah said the platform incorporates Radar Leakage Suppression technology and advanced sensing capabilities that enable accurate height measurement, stationary-object detection, and parking-lot navigation functions that are difficult to achieve using conventional UWB systems.
Growing Adoption Across the Automotive Industry
The product launch comes as automotive manufacturers increasingly integrate radar-based sensing technologies to support driver assistance and safety functions.
According to Calterah, cumulative shipments of its mmWave radar chips exceeded 30 million units during the first quarter of 2026. The company said its products are currently deployed across vehicle models from more than 30 automotive manufacturers.
Founder and Chief Executive Officer Dr. Jiashu Chen said combining mmWave radar and UWB technologies allows vehicle manufacturers to create a more connected and intelligent user experience.
“Combining mmWave and UWB technologies creates a seamless, safe, and intelligent driving experience—from car locating, unlocking, and assisted driving, to automated parking, car locking, child presence detection (CPD), and intrusion alerts,” Chen said.
As regulatory requirements continue to expand and automakers seek more advanced perception systems, radar technologies are expected to play an increasingly important role in both vehicle safety and automated driving applications.
