Abstract: In a distance detection method, a target apparatus receives a first transmit signal from a detection apparatus. The target apparatus generates a first echo signal by modulating some of reflected signals of the first transmit signal to cause a first Doppler shift between the first echo signal and the first transmit signal. The target apparatus emits the first echo signal to the detection apparatus, which derives its distance from the target apparatus based on the first echo signal.
