NXP Boosts 4D Imaging Radar Chip Production

The L2+ segment, which was not well served by classical high-resolution sensors, will now benefit from 4D imaging radar sensing with up to six corners, front and rear radar sensors in 360-degree surround fashion.

NXP Semiconductors has declared two updates to its automotive radar portfolio, as the industry’s first dedicated 16nm imaging radar processor, the NXP S32R45, has been released into mass production, with an initial customer ramp-up starting in the first half of 2022.

“NXP’s new imaging radar processors are shaping the way vehicles understand the world around them by creating high-resolution images that enhance the detection and classification of objects, a key step in improving road safety and saving lives. The extended S32R family line-up harnesses our leadership in radar processing, super-resolution algorithms and advanced MIMO waveforms to deliver the benefits of imaging radar to the rapidly growing L2+ vehicle segment.” Said Torsten Lehmann, EVP and GM, Radio Frequency Processing, NXP.

Together these processors serve the L2+ through L5 autonomy sectors, enabling 4D imaging radar for 360-degree surround sensing.

NXP’s 4D imaging radar is the first to deliver concurrent 3-in-1 multi-mode radar sensing across short-, mid-and long-range operations, enabling the simultaneous sensing of a very wide field of view around the car. To achieve this, NXP leverages an innovative architecture to boost performance beyond raw sensor hardware capabilities with a low-complexity sensor configuration utilizing 192 virtual antenna channels.

The boost is enabled by the combination of proprietary radar hardware acceleration which can deliver up to 64x the compute performance of standard processors, super-resolution radar software algorithms to achieve sub-degree angular resolution and advanced MIMO waveforms that allow simultaneous operation of antenna channels.

This architecture also helps overcome the limitations of other high-resolution sensors like LIDAR and high antenna count massive MIMO radar, whose cost and complexity limit their applications to a narrow set of use cases.

The introduction of the S32R41 delivers the industry’s first 16nm radar processor tailored for L2+ autonomous driving applications, which some industry analysts project could account for close to 50% of vehicle production by 2030.

The L2+ segment, which was not well served by classical high-resolution sensors, will now benefit from 4D imaging radar sensing with up to six corners, front and rear radar sensors in 360-degree surround fashion.

The S32R45 radar processor is the flagship of NXP’s 6th generation automotive radar chipset family. It helps to enable increasingly autonomous driving, from L2+ through the most demanding L5 use cases, where more than ten imaging radar sensors per vehicle may be required. It also addresses transportation, traffic management and other industrial applications where reliable high-resolution sensing is required.
