Radar sensor enables highly sensitive vehicle interior monitoring systems
With the onset of spring, temperatures are rising again with summertime highs. But rising temperatures also mean that it quickly gets up to 70°C in parked vehicles: A danger for children or animals left in the car. Equipped with Infineon’s Xensiv 60 GHz radar sensor (BGT60ATR24C), in-cabin monitoring systems (ICMS) detect the smallest movements as well as vital signs of small children or animals left behind and sound the alarm. In addition, the compact and cost-effective chipset is suitable for applications such as radar front-ends for gesture recognition, high-resolution frequency modulated continuous wave (FMCW) radars for range finding, short-range sensing, and hidden sensor applications in the radome.
The BGT60ATR24C enables 4-GHz FMCW operation with extremely wide bandwidth in a small package. Sensor configuration and data acquisition are accomplished via a digital interface. The integrated state machine also enables independent data acquisition with power mode optimization for low power consumption. The size- and space-optimized solution has two transmit channels (TX) and four receive channels (RX) and offers excellent thermal management.
Furthermore, the radar sensor enables additional functions, such as a reminder to wear a seat belt. This results in a cost-effective solution that further improves the safety of vehicle occupants. The sensor is qualified for automotive applications according to AEC-Q100/101.
