Infineon DEMO-BGT24ATR22-YPA XENSIV™ 24GHz Automotive Radar Sensors Demo Board
Shenzhen Mingjiada Electronics Co., Ltd. is a globally renowned distributor of electronic components, offering immediate availability of Infineon's DEMO-BGT24ATR22-YPA demonstration board. Its core evaluation focus is the BGT24ATR22 radar sensor chip. Designed specifically for the 24GHz ISM band, this chip is a flagship product meeting automotive short-to-medium range detection requirements.
【DEMO-BGT24ATR22-YPA Demonstration Board Overview】
The DEMO-BGT24ATR22-YPA demonstration kit employs the XENSIV™ BGT24ATR22 YPA shield, mounted via Hirose connectors onto the radar base board MCU7. It operates in either pulse Doppler or (B)FSK mode and is compatible with the Radar Development Kit (RDK) and Radar Fusion GUI, enabling straightforward radar sensor configuration and immediate radar signal display. The XENSIV™ BGT24ATR22 YPA shield incorporates the BGT24ATR22 24 GHz radar sensor with 2Tx, 2Rx Yagi patch antennas integrated onto the board, utilising Rogers PCB material. Furthermore, the DEMO-BGT24ATR22-YPA can be used with other hardware such as the Radar Base Board MCU7 Plus and XENSIV™ sensor shields.
1. Chip-level high-performance assurance
The BGT24ATR22 itself is a highly integrated monolithic microwave integrated circuit (MMIC). It incorporates a low-phase-noise voltage-controlled oscillator (VCO), automatic frequency control (AFC) unit, 12-bit analogue-to-digital converter (ADC), and digital radar data processing unit, providing a complete hardware foundation for generating and receiving high-quality radar analogue signals. Designed to meet stringent AEC-Q100 automotive standards, it operates within a temperature range of -40°C to 105°C, ensuring reliability and longevity in extreme automotive environments.
2. System-level demonstration via the evaluation board
Engineers can directly evaluate the performance of complete radar systems based on this chip using the DEMO-BGT24ATR22-YPA evaluation board. Referencing the technical specifications of Infineon's Demo Position2GO radar development kit from the same series provides insight into the typical capability boundaries of such evaluation boards:
Detection Performance: Theoretical detection range spans 1 to 20 metres, with typical human target detection up to 12 metres. Range accuracy reaches ±0.2 metres at distances exceeding 0.6 metres.
Field of View and Resolution: Horizontal field of view (FoV) reaches 76°, enabling lane-level wide-area detection; Distance resolution reaches 0.9 metres, sufficient to distinguish vehicles or obstacles in adjacent lanes.
Flexible Configuration: Supports adaptable settings for key parameters including frame rate, linear frequency-modulated pulses per frame (Chirps), and sampling points per Chirp. This facilitates developer optimisation for specific applications such as blind spot monitoring and intrusion detection.
【DEMO-BGT24ATR22-YPA Demonstration Board Architecture and Key Technical Parameters】
The DEMO-BGT24ATR22-YPA demonstration board transforms the potential of the BGT24ATR22 chip into a plug-and-play evaluation experience. Its system architecture typically comprises an RF front-end, a microcontroller unit, and accompanying software with a graphical user interface (GUI).
Hardware Platform: The core of the DEMO-BGT24ATR22-YPA demonstration board is the RF front-end board featuring the BGT24ATR22 MMIC. Drawing parallels with Infineon's comparable development kits (e.g., Sense2GoL), this front-end board likely interfaces with a microcontroller base board (e.g., XMC4700) based on an ARM Cortex-M core. This base board handles radar waveform generation, configuration, data acquisition, and preliminary signal processing and communication.
Technical specifications for DEMO-BGT24ATR22-YPA:

Software and Development Environment: The DEMO-BGT24ATR22-YPA demonstration board typically comes pre-installed with sample firmware for the Infineon DAVE™ development environment and can be controlled via a dedicated Radar GUI. Developers can adjust radar parameters (e.g., modulation slope, frame rate) in real-time within the GUI, view raw data spectrum plots, and visually monitor target detection results, significantly accelerating the development process.
【DEMO-BGT24ATR22-YPA Core Application Scenarios】
The 24GHz radar technology represented by the DEMO-BGT24ATR22-YPA demonstration board holds extensive application prospects in automotive and industrial sectors.
Blind Spot Detection (BSD) and Lane Change Assist (LCA): These represent traditional strengths of 24GHz radar. The system continuously and accurately monitors the vehicle's rear-side blind spots regardless of weather or lighting conditions, promptly alerting the driver when vehicles approach to significantly enhance lane change safety. By 2020, global installations of such systems were projected to surge from 14 million units to tens of millions, demonstrating their market value.
Rear Cross-Traffic Alert (RCTA) and Automated Parking Assistance: During reversing manoeuvres, radar detects vehicles or pedestrians crossing rearward, effectively preventing collisions. Its precise distance measurement also facilitates obstacle detection and parking space identification during parking operations.
Industrial and Consumer Sensing: Applications for 24GHz radar extend far beyond automotive. It can be employed in:
Smart Homes: Enabling contactless lighting and switch control, detecting human presence, and performing basic gesture recognition – offering greater privacy protection than cameras.
Industrial Automation: Material detection, equipment condition monitoring, and personnel safety protection in harsh environments such as dust or mist.
Traffic Monitoring: Vehicle counting, speed measurement, and flow analysis.
