Amplified High-Definition Radar Accelerates Assisted Driving Systems Functionality
In the realm of automotive technology, Distributed Aperture Radar (DAR) is making waves as an innovative solution for advanced driver-assistance systems (ADAS). The purpose of DAR is to improve a vehicle's environmental perception by creating a large virtual radar aperture from multiple small, low-cost radar sensors [1].
Functionally, DAR consists of multiple radar units distributed around the vehicle that operate coherently as a modular system, fusing data from overlapping fields of view. This coherent sensor fusion enables high-resolution sensing, improved angular resolution, enhanced detection accuracy, lower power consumption, and simplified system integration for Original Equipment Manufacturers (OEMs) [1].
The collaboration between NXP and Zendar is at the forefront of this technological advancement. They are jointly developing DAR technology, leveraging NXP's S32R radar processor platform and RFCMOS SAF8xxx one-chip SoCs, as well as Zendar's DAR software [1].
The PurpleBox reference design, developed by NXP, is a testament to this collaboration. It includes an SAF8544 radar one-chip SoC, TJA1120B 1000Base-T1 Ethernet transceiver, an optimized FS56 system basis chip, and PF51 power-management IC in a small sensor form factor. The PurpleBox is a reference design for distributed radar sensor architectures that aggregates and processes four-corner radar sensors, producing a high-density surround point cloud [1].
The PurpleBox radar processor reference design is designed to run Zendar's DAR software, catering to the diverse architectures of car OEMs. The radar bridge, a dedicated processor designed to manage and fuse data from multiple radar sensors in a vehicle, enhances object detection accuracy, reduces false positives and negatives, and minimizes latency in safety-critical ADAS functions [1].
The Pluto radar reference design allows customers to evaluate corner and front radar applications. The PurpleBox, another reference design from NXP, is a comprehensive software development environment and a PCIe interface for attaching a mass storage device or a machine-learning accelerator [1].
The DAR technology has the potential to accelerate ADAS development and make autonomous driving more accessible. By leveraging multiple small sensors, DAR provides superior high-resolution, low-power, multi-angle environmental perception critical for next-generation ADAS and autonomous driving [1].
In an automotive landscape where radar is a cost-effective and dependable sensor solution, even in challenging conditions such as fog, darkness, and rain, DAR technology is set to revolutionise the industry [1].
