• NXP's flagship S32R45 and new S32R41 processors meet L2+ to L5 autonomous driving requirements for building 4D imaging radar for 360-degree surround perception
  • The S32R series radar processor is based on a general architecture, provides a scalable radar development platform for different levels of autonomous driving, and supports software reuse
  • At CES, NXP and CubTEK will jointly demonstrate imaging radar technology and introduce upcoming Radar Technology Days


CES 2022, Las Vegas, USA – January 7, 2022 – NXP Semiconductors NV (NASDAQ: NXPI) announces two updates to its industry-leading automotive radar portfolio . Currently, 20 major OEMs around the world use NXP radar processors in their designs. As the industry's first dedicated 16nm imaging radar processor, NXP's S32R45 has already been put into mass production and will be used for customer mass production for the first time in the first half of 2022. In addition, NXP has introduced a new radar processor, the S32R41, which extends the benefits of 4D imaging radar to more cars. These two processors can meet the needs of L2+ to L5 autonomous driving, and are used to build 4D imaging radars to achieve 360-degree surround perception.

Imaging radar expands the capabilities of radar, in addition to detecting large objects, it also senses the environment around the car through high-resolution point clouds, thereby enhancing environmental mapping and scene perception. In complex urban scenes, these images can be used to classify a variety of objects, including vulnerable road users and cars, such as motorcycles driving close to large cargo trucks, and children entering the driveway from between parked vehicles. In addition, imaging radars must be able to measure and classify the velocity of targets up to 300 meters away, far beyond the range of the human eye. It must also be able to identify fast-moving cars, distinguishing them from slow-moving cars and even static obstacles, such as a dropped tire in the driving lane. With the introduction of new imaging radar processors, NXP is able to meet all of these needs.

NXP's 4D imaging radar is the first to provide short-range, medium-range, and long-range concurrent multi-mode radar sensing, which can simultaneously sense a wide field of view around the car. To achieve this goal, NXP leveraged an innovative architecture to improve the performance of the original sensor hardware by configuring low-complexity sensors to achieve 192 virtual antenna channels. NXP's 4D imaging radar uses proprietary radar hardware accelerators to achieve 64 times the computing performance of standard processors, applies super-resolution radar software algorithms to achieve angular resolution of less than 1 degree, and applies advanced MIMO waveform design to support simultaneous operation of multiple antenna channels , so as to improve the performance of the radar sensor. The architecture also helps overcome the limitations of other high-resolution sensors, such as lidar and multi-antenna Massive MIMO radar, which are limited to a small number of use cases due to cost and complexity constraints.

Torsten Lehmann, executive vice president and general manager of NXP's RF Processing business unit, said: "NXP's new imaging radar processor can generate high-resolution images to enhance detection and classification of objects, thereby changing the way cars perceive their surroundings, This is an important measure to improve road safety and save lives. The expanded S32R product family takes full advantage of our leadership in radar processing, super-resolution algorithms, and advanced MIMO waveforms to play imaging radar in the fast-growing L2+ automotive field effect."

NXP Imaging Radar Product Updates

The launch of the S32R41 processor brings the industry's first 16nm radar processor tailored for L2+ autonomous driving applications, and according to industry analysts, L2+ autonomous vehicles may account for nearly 50% of total vehicle production by 2030 %. Traditional high-resolution sensors cannot meet the needs of the L2+ automotive market well, and now, thanks to 4D imaging radar sensing technology, we can use up to six corner radar sensors, forward-facing radar sensors, and rear-facing radar sensors, Realize 360-degree body surround perception.

The S32R45 radar processor is the flagship in NXP's 6th generation automotive radar chipset family. It helps enable higher levels of autonomous driving, supporting L2+ to demanding L5 use cases, where more than ten imaging radar sensors may be required per vehicle. The processor is also capable of addressing transportation, traffic management and other industrial applications that require reliable high-resolution sensing.

NXP's S32R45, S32R41 radar processors, combined with NXP's TEF82xx RFCMOS transceivers, provide high angular resolution, powerful processing power and wide sensing range, all of which are required for mass-produced imaging radar solutions. The S32R platform provides a common architecture for software reuse and rapid development, as well as a high-performance hardware security engine that supports OTA updates and complies with new network security standards.

NXP Exhibits at CES 2022 (Booth [CP-18])

At CES, visitors to NXP's booth can watch live demonstrations of NXP's imaging radar sensors. Built by NXP in collaboration with radar platform and ADAS application specialist CubTEK, this imaging radar sensor provides image-like sensing and angular resolution on the order of less than 0.1 degrees for enhanced 4D sensing.

Due to the implementation of strict new crown epidemic prevention and control, NXP invites visitors to the exhibition to reserve a visiting time slot in advance to watch the real-time demonstration of the S32R45 imaging radar system.

NXP Imaging Radar Technology Days to be held on 23-24 February 2022

Following CES, NXP also invited radar and ADAS platform developers to attend the Imaging Radar Technology Day online at the end of February to gain a deeper understanding of imaging radar technology.
