Original Abstract Submitted
provided is a distance-measurement apparatus capable of preventing incorrect distance measurement. a generation unit generates a plurality of transmission pulses having frequency offsets different from each other. a transmission unit repeatedly transmits the transmission pulses generated by the generation unit. the reception unit receives reflected pulses of the respective transmission pulses reflected on a distance-measurement-target object. a detection unit detects frequency offsets of the reflected pulses received by the reception unit. a distance calculation unit calculates a distance to the distance-measurement-target object based on receiving timings of the reflected pulses received by the reception unit and transmitting timings of the transmission pulses corresponding to the frequency offsets detected from the reflected pulses. an invalidation processing unit performs processing of invalidating distance calculation processing for a certain period based on the transmitting timings of the transmission pulses.
