Abstract
The present invention provides an in-vehicle passenger detection system and method using an Ultra-Wide Band radar. The present invention processes the values collected using an Ultra-Wide Band radar in the time domain, so that it is possible to detect passengers in a vehicle faster than the time required to process the collected values in the frequency domain using a conventional Ultra-Wide Band radar. Also, the present invention detects a large motion, such as a passenger's hand or foot movement in a vehicle, and a small motion, such as a passenger breathing quietly, using separate data processing procedures, respectively, so that faster and more accurate passenger detection is possible.
