Patent abstract
A distance measuring device includes: an impulse generator that generates an impulse; a transmission antenna that transmits the impulse generated by the impulse generator; a reception antenna that receives a reflected signal of the impulse transmitted from the transmission antenna and reflected by the object, and a leakage signal of the impulse transmitted from the transmission antenna; and a distance calculator that calculates the distance to the object, based on the time difference between the reflected signal and the leakage signal received by the reception antenna.
