LOCATION DETECTING DEVICE AND METHOD THEREOF

摘要

A location detection device which detects a location of an object according to an embodiment of the present invention includes: a sensor unit including a plurality of sensors which are adjacently arranged with each other; a flight time calculation unit for calculating flight times using a reflection signal with respect to a transmission signal of the respective sensors; and a coordinate calculation unit for calculating a coordinate of the object based on the calculated flight times.
