About

Radar sensors for automotive ADAS applications

With the rise of autonomous driving, radar has become a cornerstone technology for long-range, all-weather environment sensing. Infineon's 77 GHz ADAS radar portfolio delivers the performance, reliability, and scalability required for today's safety-critical automotive applications and tomorrow's automated driving features.

Our 77 GHz FMCW radar transceivers (CTRX), built on advanced 28 nm technology, enable high-resolution sensing with dense point clouds and precise range, angle, and velocity information. They support fine object detection, separation and classification for high-fidelity imaging radar and offer flexible cascading for multi-channel, multi-antenna systems with enhanced field of view and angular resolution.

Optimized for centralized radar architectures and future domain and zonal ECU concepts, Infineon's 77 GHz radar solutions support automotive applications such as ACC, LCA, highway and traffic assist, parking assist, and AEB. Mounted in the corners and front of the vehicle, they enable high-quality environmental perception and support safer, more automated driving, enabling next-generation autonomy at level 2+ and beyond.

Raw radar data to central compute for superior fusion and scalability

Centralized radar overcomes the compute and memory limitations of traditional radar modules by sending rich raw sensor data directly to a high-performance central computer. This preserves the full information content for multi-sensor fusion and enables scalable performance through advanced, software-defined signal processing algorithms.

Infineon's 77 GHz automotive radar solutions are purpose-built for these centralized radar concepts, empowering future-proof, software-defined vehicles and AI-driven autonomous driving systems. By moving computation from the radar module to a powerful central processor, OEMs can leverage greater compute and memory resources to fully exploit 77 GHz radar capabilities. Combined with data from other sensors, this architecture delivers higher-quality environmental perception and enables one of the most optimized distributed automotive radar concepts available from Infineon.

Scale to high channel counts for crisp environment imaging and detail

Perceive the environment in exceptional detail and detect, track, and classify moving objects at long ranges with Infineon's 77 GHz imaging radar solutions. These demanding autonomous driving applications require high channel counts to generate a crisp radar "image" of the surroundings. With Infineon's powerful cascade feature, you can scale systems to 48 transmit and 48 receive channels and beyond, unlocking high-resolution point clouds and superior object detection and separation. And this is only the beginning: stay tuned for our upcoming products with even higher channel integration and next-generation cascading capabilities, enabling the next level of ADAS automotive perception.

Infineon's CTRX radar features digital PLL and a flexible sequencer

Infineon's CTRX 77 GHz FMCW radar transceivers feature an advanced digital PLL architecture that delivers faster flyback and exceptional phase stability, enabling high SNR and best-in-class object detection and separability of objects at longer distances for automotive ADAS applications. A highly flexible sequencer allows you to tailor 77 GHz radar configurations precisely to your application, from long-range automotive sensing to high-resolution imaging radar.

Tailored radar kits to speed design, testing, and time to market

Accelerate your automotive ADAS radar development with Infineon's tailored 77 GHz radar evaluation kits, purpose-built to meet the demands of modern automotive applications. Whether you need cascaded high-channel-count radar systems for high-resolution imaging radar, centralized radar kits with high-speed interfaces to standard high-performance central compute units, or edge radar kits with pre-installed firmware delivering ready-to-use dense point clouds, our automotive radar evaluation platforms are engineered to shorten design cycles, reduce development costs, and speed time to market for your next-generation ADAS radar system.

Unified configuration tools and drivers with one interface

Use Infineon's ramp design tool, radar configuration drivers, and software to streamline your automotive ADAS radar development. A common interface across multiple radar products in the Infineon ADAS radar family simplifies system configuration, accelerates automotive radar design cycles, and enables easy reuse of software and know-how across hardware platforms.
