Abstract: An occupancy detection apparatus and a method for controlling the same are disclosed. The occupancy detection apparatus may include a transmitter including one transmission antenna for outputting a transmission signal, a receiver including a first reception antenna and a second reception antenna, each for receiving a reflected signal corresponding to the transmission signal, and a processor for eliminating a background signal corresponding to a background from each of the reflected signals, and extracting a signal reflected from an occupant from each of the reflected signals by extracting a correlation between the transmission signal and the reflected signal free of the background signal.
