Leveraging a coherent demodulation architecture and advanced ranging algorithms, it Is capable of delivering exceptional distance and angle measurements in the complex in-cabin environment, enabling gesture recognition and intruder alarm features. It delivers Breath Per Minute (bpm) detection for CPD with less than 1bpm resolution, exceeding the Euro NCAP requirements. The CEVA UWB Radar solution is an add-on software package to the CEVA RivieraWaves UWB PHY and MAC IP. In addition, by reusing the Secure Digital Key UWB anchor points which are increasingly common in automobiles, UWB-based CPD can be economically deployed across the automotive market - from premium to budget. Using UWB radar sensors rather than alternative camera-based sensors also address the privacy concerns of in-cabin sensing systems, as well as supporting low-light operation. In-cabin radar based on UWB is being seen as an exciting technology solution for presence sensing, as its capable of detecting even micro movements right down to breathing rate. In China, CNCAP is similarly promoting CPD and in the US the Hot Cars Act has been passed – the NHTSA is now reviewing CPD guidance. In Europe, Euro NCAP is actively promoting CPD through its safety rating metrics. Child Presence Detection is a safety system designed to detect and alert if a child or pet is accidently left behind in the vehicle.
