Abstract

A distance measuring apparatus includes: a DTC generator unit that generates DTC signals having edges delayed to define time segments; a template generator unit that generates template signals consecutively in a pre-designated number within the time segments in response to the DTC signals; a coarse time determiner unit that determines the time segment in which a delayed signal is received by calculating correlations with the consecutively generated template signals; a fine time measurer unit that determines the time at which the delayed signal is received within the time segment determined at the coarse time determiner unit from the results of calculating correlations between multiple template signals within the determined time segment and the delayed signal; and a distance calculator unit that calculates the total delay duration of the delayed signal and calculates the distance to the measurement target object from the calculated delay duration.
