Radar development kit

At Bauma, Infineon presents a radar development kit. It contains a member of the BGT24A transceiver MMIC family and a member of the Aurix 32-bit radar micro-controller family with CAN connectivity.

The growing symbiosis between a vehicle and its environment offers opportunities for cross-vehicle improvements, not only for private cars but in the construction area as well. For example, active safety systems warn the driver or actively intervene in the driving process, avoiding or minimizing the effects of collisions. Examples of this type of safety system include pedestrian detection, distance warning, and blind spot assist.

Many active safety systems employ radar technology in the form of chips that send and receive electronic waves in a high frequency range. Compared to other, mostly camera-based, driver assistance technologies, radar works reliably in any situation – even in difficult visibility conditions caused by snow, fog, heavy rain, or dazzling backlight.

At Bauma 2016, Infineon presents its Automotive 24 GHz radar development kit that allows users to implement and test 24 GHz automotive radar applications based on frequency shift keying or frequency modulated continuous wave range/position measurements. It contains a member of the BGT24A transceiver MMIC family (for example, BGTA24ATR12) and a member of the Aurix 32-bit radar micro-controller family (for example, SAK-TC264DA-40F200) for high-performance signal processing. The device has a fast Fourier transform acceleration engine and extended on-chip memory for radar image storage.

The 32-bit multicore Aurix ADAS derivative offers a dedicated feature set for radar applications, which can eliminate the need for additional DSP, external SRAM, and external ADC ICs, enabling customers to implement short-range radar functionality. The Aurix SAK-TC264DA-40F200 micro-controller has built in CAN connectivity with five CAN nodes. It supports CAN and CAN FD, as well as Flexray, LIN, and SPI.

The 24-GHz transceiver is a SPI controlled solution comprising a VCO, power amplifier, frequency dividers, multiple sensors, and two complete IQ receivers.

Visitors can find Infineon at its partner’s booth, TTControl in hall A5, booth 450.
