At bauma 2016 (April 11-17, 2016) in Munich, Infineon is presenting its latest 24 GHz radar solution, which was developed for the modern, radar-based assistance systems in trucks and construction machines. It is a highly integrated system, which contains not only the BGT24ATR12 24 GHz radar chip but also the corresponding AURIX™ microcontroller, specifically customized for radar applications and the appropriate power supply.

Thanks to semiconductor solutions from Infineon, radar-based assistance systems are becoming more compact and cheaper to install. By 2020, the number of such systems could be increased significantly, not only in the approximately 3.6 million trucks that are expected to be produced by then, but also in buses, agricultural vehicles, construction and mining machines and in cars.

Infineon’s radar chips send and receive the high-frequency 24 GHz signals and transmit them to the AURIX microcontroller in the radar electronic control unit for further processing. The AURIX ensures the reliable and quick processing of the information, which the radar chip captures around the vehicle and transmits to the driving assistance system.

Because the AURIX is so efficient, 24 GHz radar systems will be more compact, smaller and cheaper than today, since it will be possible to dispense with other chips that were previously needed. These redundant chips include, for example, the digital signal processor, memory chips and various analog-digital converters, which change the radar chip’s analog signals into digital signals that can be processed by the microcontroller. All members of the AURIX family have a very high data processing rate and thus a high real-time performance; they are among the best microcontrollers currently available on the market.
