摘要： Disclosed is a distance measuring system comprising a transmitter that sequentially generates pulse sequences each having a plurality of pulse signals of equal amplitudes arranged at equi-time intervals, and transmits the generated pulse sequence as a radio wave; and a receiver that receives the pulse sequence transmitted from the transmitter as a radio wave, and has a distance calculator that acquires propagation times of the pulse signals in the received pulse sequence, and calculates a distance from the transmitter by giving different weightings to the pulse signals for the propagation times acquired for the respective pulse signals. As the amplitudes of the pulse signals in the received pulse sequence become larger, the weightings are made larger.

The coordinator (3) fixes a position of the end of the beacon (21) with respect to a beacon slot constituting a superframe, and generates the beacon (21) where a start of a preamble part (32) is extended toward a start of the beacon slot over a time To. The devices (2) are synchronized with the coordinator (3) via an end time of the beacon slot detected from an end time of the preamble part (32) in the beacon frame.
