Automotive Anti-Abandon Systems: a Millimeter-Wave Radar Sensor for the Detection of Child Presence

摘要

This paper presents an innovative methodology for detecting the presence of a child in the car seat or on the back seat of the vehicle. The goal of this project is to avoid the incidents where children being left inside a car die of heatstroke.The core of the system is represented by a radar whose transmitted signal has been modulated by a saw-tooth waveform from the 79 to 81 GHz. The capability of the system to detect a child or an infant has been demonstrated by means of a properly tailored simulation scenario. Moreover, the transmitting/receiving antenna array has been designed in planar technology and the relevant parameters have been reported.
