PROBLEM TO BE SOLVED: To provide a laser radar device that can reduce a dead angle occurring due to adherence of dust even when the dust adheres to a housing window.SOLUTION: A laser radar device 1 comprises: a housing window 3 that is attached to a housing; a laser projection unit 5 that projects laser light; and a scan unit 6 that irradiates the laser light from the housing window 3 as periodically scanning the laser light projected by the laser projection unit 5, in which a scan angle range in a horizontal direction where the scan unit 6 scans the laser light is restricted to a part of 360 degrees. The housing window 3, which is rotatable around a vertical axis direction, comprises: a dust determination unit that determines whether dust adheres to the housing window 3 of a location where the laser light is irradiated; a drive unit 8 that rotates the housing window 3; and a drive control unit that, On the basis of the determination of the dust determination unit that the dust adheres to the housing window 3, drives the drive unit 8 to rotate the housing window 3.SELECTED DRAWING: Figure 4 |
