Abstract
A radar device can reliably, and rapidly detect dirt adhered to a radome surface without misdetection. The radar device includes a transmit/receive shared antenna () that transmits an electric wave to an object and receives a reflected wave that has been reflected from the object, a mixer () that mixes a transmission signal and a reception signal together to generate a beat signal, and a signal processing unit () that measures a distance to the object and a relative speed of the object on the basis of the beat signal. The transmit/receive shared antenna () modulates an unmodulated wave into a pulse and transmits the pulse modulated wave at a specific timing. In the case where the unmodulated pulse is transmitted, the beat signal that has been generated by the mixer () is converted into a digital voltage value by an A/D converter (). The signal processing unit () detects the dirt that is adhered to the radome () of the transmit/receive shared antenna () on the basis of an output of the A/D converter
