With spring, temperatures are rising again to reach highs in summer. But rising temperatures also mean that it quickly becomes up to 70°C inside parked vehicles: A danger for animals and children left behind in the car. Equipped with the XENSIVTM 60 GHz automotive radar sensor (BGT60ATR24C) from Infineon Technologies AG, in-cabin monitoring systems (ICMS) detect micro-movements as well as vital signs of left-behind infants and animals and sound the alarm. In addition, the compact and cost-effective chipset addresses applications such as front-end radar for gesture sensing, high-resolution frequency modulated continuous wave (FMCW) radars for distance measurement, short range sensing operations, as well as hidden sensing applications in the radome.

The BGT60ATR24C enables 4 GHz ultra-wide bandwidth FMCW operation in a small package. Configuration of the sensors and data collection are done with a digital interface. The integrated state machine enables independent data acquisition with power mode optimization for lowest power consumption. The size- and space-optimized solution has two transmit channels (TX) as well as four receive channels (RX) and offers excellent thermal management.
