Radar Sensors

Radar offers a host of advantages over passive infrared (PIR) technology in motion detection applications. These include greater accuracy and more precise measurement of detected objects, paving the way for new capabilities in speed detection and motion sensing. These advanced capabilities enable many consumer goods such as robots, cars, smart home devices, and even lights to “see” their surroundings and respond dynamically.

Designed to support a wide range of industrial, consumer and automotive applications, Infineon’s millimeter wave (mmWave) radar portfolio offers both FMCW as well as Doppler radar sensors supporting 24GHz, 60GHz, 77/79 GHz.

Additionally, Infineon offers the smallest 24GHz Monolithic Microwave Integrated Circuits (MMICs) in the market. Thanks to the broad portfolio of automotive qualified 24GHz, 60GHz, and 77/79 GHz front-end radar MMICs (RASIC™), a full range of application can be supported from safety-critical applications such as automatic emergency braking up to driver assistance systems.

Infineon’s radar sensor portfolio includes 24GHz, 60GHz, as well as 77/79 GHz mmWave radar sensors, serving a wide range of automotive and IoT applications. Most commonly, radar sensors are used in motion detection triggering systems such as indoor and outdoor lighting solutions, automatic doors, camera and security systems, or smart home devices. Additionally, object detection can be ensured through the application of radar sensor and motion sensor ICs, since they can determine the direction of a moving object, speed of an object, distance, and depending on the antenna configuration, even the position of a moving object.

Key benefits include:

• Direction, proximity, and speed detection
• Segmentation and tracking functionalities
• Target positioning
• Detection through non-conductive materials
  • Product design flexibility
  • Anonymous sensing
• Maintains operation through harsh environmental conditions such as rain, snow, fog, dust, etc.
• Sensitive enough to capture breathing and heartbeat – Radar can feel presence & vital functions
• Radar performance parameters can be adjusted – Adaptable to different application requirements

For more than 10 years, Infineon has been offering high-quality and reliable radar sensors for the automotive industry. Our 77GHz chips are capable of recognizing objects at ranges up to 250 meters away while our on-chip sensors allow for better calibration and monitoring of temperature, output power, and multiple monitors/supervisory circuits.

The single 77/79GHz radar platform supports all types of radar applications and offers automakers greater flexibility by offering numerous configuration parameters and on-chip monitoring functions. Infineon now also offers 60 GHz radar sensors for many different automotive applications.

Infineon’s selection of radar solutions for industrial and consumer applications includes fully integrated microwave radar motion sensors with Antennas in Package (AIP), as well as built-in detectors for motion and direction of motion. With a power consumption of less than 5mW, the radar sensors bring innovative, intuitive sensing capabilities to many applications.

Based on the developed algorithm the MMIC can serve established as well as new applications and use cases without intruding on privacy. Moreover, Infineon’s radar sensor technology offers a smart and cost-effective replacement for conventional PIR sensors in low power or battery-powered applications.
