PROBLEM TO BE SOLVED: To provide a radar device having an improved S/N ratio by further reducing an influence of disturbance light. SOLUTION: The radar device 1 includes: a transmission section 10 for successively irradiating a prescribed irradiation angle range with laser beams; a light receiving element array 34 where a plurality of light receiving elements are arranged to receive reflection light where laser beams are reflected by an object; a light receiving lens 32 for condensing reflection light in the light receiving element array; and an operation section 60 enabling detection of a light-receiving element corresponding to irradiation angles of laser beams emitted from the transmission section 10 in a plurality of light receiving elements for composing the light receiving element array 34. The radar device 1 detects an object based on a signal received by the light receiving element array 34. The radar device 1 also includes two light receiving lenses 32A, 32B having mutually different optical axes as the light receiving lenses 32. COPYRIGHT: (C)2010,JPO&INPIT |
