In an automobile radar apparatus according to the present invention, a light-receiving optical system is rotated in response to an output from an image formation position calculation unit in such a manner that light source is focused on a vertical plane containing an optical axis of the light-receiving optical system; a direction up to the preceding vehicle is calculated from a turning angle in response to an output derived from an angular detecting unit; and a distance up to the preceding vehicle is calculated from an image position of the light source based upon an output derived from the image formation calculation unit.
