Abstract: Provided is a laser radar system. The laser radar system includes a first transmission and reception unit sequentially radiating a first laser beam to a plurality of locations within a first view range and receiving a reflected light; and a second transmission and reception unit sequentially radiating a second laser beam to a plurality of locations within a second view range and receiving a reflected light, wherein each of the first transmission and reception unit and the second transmission and reception unit is fixed to a loader and independently searches for the first view range and the second view range.
