Single-Channel FMCW-Radar-Based Multi-Passenger Occupancy Detection Inside Vehicle

In this paper, we provide the results of multi-passenger occupancy detection inside a vehicle obtained using a single-channel frequency-modulated continuous-wave radar. The physiological characteristics of the radar signal are analyzed in a time-frequency spectrum, and features are proposed based on...
