ABSTRACT:
A distance measurement sensor and a distance measurement method using the same are disclosed. The distance measurement sensor can use all of a pulse method and a Continuous Wave (CW) method, can select an appropriate measurement method according to the distance to be measured, thereby accurately measuring the distance. The distance measurement sensor solves the reception-signal limitation caused by a transmission leakage signal in the case of the CW method, reduces an amount of power consumption, measures distances of several objects at the same time, and establishes the range of the distance.
