Abstract
An event detection system for a vehicle includes a transmitter and a receiver. The transmitter is disposed at a first position adjacent to a boundary of a space provided in the vehicle, including a first antenna having a transmitting direction, and the receiver is disposed at a second position adjacent to the boundary, which communicates with the transmitter and includes a second antenna having a receiving direction. The transmitter sends a probe signal toward the transmitting direction, and the receiver receives the probe signal. The receiver stores preset CSI. The preset CSI includes a first CSI and a normal CSI, the receiver obtains a current CSI from the probe signal by performing a time-reversal process, and to compare the current CSI to the preset CSI. When the first CSI is matched to the current CSI, a first event associated with the vehicle is determined to be occurred.
