Abstract
A high-precision distance measuring with a reduced error in a distance measuring system which calculates a distance from an arrival time of each pulse signal constituting a pulse sequence is provided. For an oscillator which generates pulse signals by counting the number of pulse signals constituting a received pulse sequence, a relative time difference between a transmitting device and a return device is acquired, a distance from the transmitting device to the return device is calculated, and the calculated distance is corrected based on the calculated relative time difference.
