Abstract
A distance measuring apparatus includes: a digital-to-time converter (DTC) configured to receive a clock signal and output a pulse corresponding to a provided code; an in-phase (I) template generation part configured to be triggered by the pulse output from the DTC to generate an I template impulse signal; a quadrature (Q) template generation part configured to be triggered by the pulse output from the DTC to generate a Q template impulse signal; and an I correlator configured to perform demodulation with the signal reflecting off the target and the I template impulse signal, and a Q correlator configured to perform demodulation with the signal reflecting off the target and the Q template impulse signal, wherein the distance measuring apparatus converts a result of demodulation into a digital code to measure the distance to the target.
