Abstract
An automotive radar device that can securely detect dirt adhering to the surface of a vehicle-side radome irrespective of the positional relation between the vehicle-side radome and a radar. The automotive radar device has a radio-type radar housed in a vehicle-side radome installed on a vehicle, the radio-type radar including a transmitting unit and a receiving unit. The automotive radar device sends and receives radio waves from the radar through the vehicle-side radome and measures distance and relative velocity with respect to a subject. The automotive radar device includes a guiding unit that is arranged between the vehicle-side radome and the radar and that guides a reflected wave from adhering matter on a surface of the vehicle-side radome to the receiving unit of the radar, and an adhering matter judging unit that judges the existence/non-existence of the adhering matter on the surface of the vehicle-side radome on the basis of signal level of the reflected wave received by the receiving unit.
