SOC/FPGA: 4D full-range radar
The 4D radar developed by ZF supports the development of safe vehicles by generating a high-resolution point cloud. The SCS team has implemented the necessary signal processing on a SOC/FPGA.
-
The challenge
A 4D radar places the highest demands on the computing power of a hardware device. Pre-processing such as FFT and peak search are very well suited to being calculated in the FPGA/PL part of a modern MPSoC. Post-processing, e.g. tracking, can then be calculated on an ARM core of the device.

SCS solution
The algorithm to be implemented was developed by our customer's radar specialists. As an AMD Xilinx Premier Partner, SCS has optimised, implemented and tested these algorithms for the Zynq Ultrascale+ architecture. SCS also supports the customer in preparing the ASIL documentation and clarifying functional safety.
-
Added value
The four-dimensional, high-resolution radar enables advanced safety and automated driving functions. The 192 channels have a resolution 16 times higher than a typical vehicle radar and enable highly detailed scene and object detection within a range of 350 metres.
Within a very short time, the customer had a functional prototype ready to carry out initial tests. In the meantime, the radar has been further developed in preparation for series production.
Project background
SCS carried out the following subtasks for the implementation of the algorithm on the FPGA:
- Guided development of an FPGA architecture for a specific algorithm

ZF Radar background
The 4D full-range radar offers a resolution close to that of optical sensors, cameras or LiDAR. This at a competitive price, while at the same time offering the possibility of direct speed measurement and the ability to work in difficult conditions (snow, fog, dust). In combination with these technologies, high-resolution radar can help to ensure the necessary safety and reliability for partially to highly automated driving, including Level 4.
The imaging full-range radar offers high resolution in four dimensions: Distance, speed, horizontal angle and additionally the elevation angle (height). This means that the radar is also an imaging technology in 3D, with speed as an additional fourth measurement dimension. The high-resolution 4D detection of the traffic situation helps a vehicle on the motorway, for example, to detect the end of a traffic jam under a bridge at an early stage and to brake accordingly.
From 2022, our customer will supply its new 4D full-range radar to the first OEM for a series production electric SUV.
