To provide a distance measuring system, a distance measuring device, and a distance measurement method with which it is possible to prevent a reduction in the accuracy of distance measurement.SOLUTION: Provided is a distance measuring system for transmitting/receiving distance measurement signals including a phase detection signal between a first and a second device, and calculating the distance between the devices on the basis of the phase detection result of the received phase detection signal. The distance measuring system comprises: a modulation circuit 18 for generating distance measurement signals including a modulated signal of an identification signal; a transmission circuit 15 for transmitting distance measurement signals to the other device; a reception circuit 16 for receiving distance measurement signals from the other device; a demodulation circuit for demodulating the modulated signal if the received distance measurement signals; and a control circuit 10 for determining the influence on the phase detection result of an interference wave on the basis of the restored state of the identification signal obtained from the demodulation result of the demodulation circuit.SELECTED DRAWING: Figure 1
