Infineon boosts 4D radar range to 380m for driverless cars
Infineon Technologies is showing final samples of its scalable 4D imaging radar chip with a detection range up to 380m for driverless cars.
The ability to detect pedestrians in dense urban environments is currently a challenge to enable the next level of automated and autonomous driving.
The RASIC CTRX8191F 77/79GHz radar millimetre IC (MMIC) chip was specifically designed to meet the requirements of SAE L2+ to L4 automated and autonomous driving autonomous with low system cost.
The chip is built on a 28nm process with improved signal to noise ratio that allows the radar to detect vulnerable road users and vehicles at a distance of up to 380 meters, up from 250m, using eight transmitters and eight receivers.
The radar chip also enables cascading of multiple devices at low frequencies, reducing the need for expensive RF materials on the circuit board and uses a launcher-on-package design that allows low-cost waveguide antennas. A digital PLL offers high flexibility in generating complex waveforms with a flyback time of under 1 µs.
The CARKIT radar development kit uses the CTRX8191F sensor prototyping module and supports various system configurations, including the transmission of raw ADC data, FFT intermediate results or radar detections via a Gigabit Ethernet interface. The included example code and graphical user interface enable rapid prototyping and design, allowing developers to implement their radar system concepts quickly and efficiently.
A waveguide antenna is included in the kit, and this can be easily replaced with a custom antenna to meet specific customer requirements.
Several versions of CARKIT are already available, including a 4D front radar configuration with eight transmitters and eight receivers, and a cost-effective corner/front radar design for the standard market with four transmitters and four receivers.
Samples of the CTRX8191F 4D radar MMIC and CARKIT modules in various configurations are available now and will be shown at CES 2025 in January.
