PROBLEM TO BE SOLVED: To suppress interference with an optical beacon signal by a simple configuration in a radar device which can be installed in a vicinity of a windshield in a vehicle interior together with a VICS device.SOLUTION: In a radar device 20, time required to detect a reception timing of a reflected wave of a transmission wave from a transmission LD by a reception PD after an emission timing of the transmission wave is defined as an observation time, and an observation time corresponding to a maximum detection distance at which a reflection target can be detected by a control unit is defined as a maximum observation time. When emission start information indicative of an emission start timing of an up-link signal is inputted from a VICS device 10 to the control unit of the radar device 20, the control unit causes the transmission LD to emit one or more transmission waves so that at least the maximum observation time is within an up-link period after the emission start timing, whereby the reflection target can be detected before the up-link signal is reflected by a windshield and is received by the reception PD. |
