A new radar solution enables precise identification of road users and vehicles up to 380 meters away.
Detecting pedestrians in dense urban environments remains a critical challenge for achieving advanced automated and autonomous driving levels. Addressing the stringent demands of SAE-defined L2+ to L4 autonomy, Infineon Technologies AG introduces the RASIC CTRX8191F, a 28nm radar MMIC designed to revolutionise radar imaging for next-generation autonomous vehicles. It delivers performance with enhanced signal-to-noise ratios, enabling precise detection of vulnerable road users and vehicles up to 380 meters away. It meets the high-performance standards required for advanced radar systems by utilising system configurations with eight transmitters and eight receivers.
The key features include:
- Detects direction, proximity, and speed
- Offers segmentation and tracking capabilities
- Enables precise target positioning
- Works through non-conductive materials
- Provides flexibility in product design
- Supports anonymous sensing
- Operates in harsh conditions
- Sensitive enough to detect breathing and heartbeat
- Adaptable radar performance for various applications
Its ability to cascade multiple devices at low frequencies reduces reliance on expensive RF materials, while an optimised launcher-on-package design simplifies the use of cost-effective waveguide antennas. Moreover, the device’s state-of-the-art digital PLL offers unparalleled flexibility in generating complex waveforms with an industry-leading flyback time of less than 1 microsecond.
The company provides the comprehensive CARKIT radar development kit, built around the CTRX8191F. This prototyping module supports diverse configurations and facilitates data transmission via a Gigabit Ethernet interface. Developers benefit from example code, a graphical user interface, and a waveguide antenna that can be replaced with custom solutions to meet specific requirements. CARKIT configurations include a 4D front radar system with eight transmitters and eight receivers for advanced applications and a cost-effective corner/front radar solution with four transmitters and receivers tailored for standard use cases.
