The target device receives the first transmission signal from the detection device. The target device generates a first echo signal, wherein the first echo signal is generated based on modulating a partially reflected signal of a first transmitted signal, and the first echo signal and the first transmitted signal have a first doppler frequency shift. The first echo signal is used to determine a distance between the detection device and the target device. Since the doppler frequency of the first echo signal is different from the doppler frequency of the echo signal from the environment, the detection device can distinguish the first echo signal from the target device according to the doppler frequency, so that the target device can be measured according to the first echo signal.)
