In this paper, we suggest features for passenger detection inside the vehicle using frequency modulated continuous wave (FMCW) radar. In radar time-frequency spectrum, the magnitude variation of a person is caused by the physiological movements such as breathing and heartbeat. To quantify the physiological movements, the power of respiratory frequency band (0.1-0.4 Hz) and heartbeat frequency band (0.8-1.7 Hz) is used. We experimentally compare the proposed features under presence and absence of a person using FMCW radar signal acquired inside the vehicle. © 2021 IEEE.
