Abstract
The present invention provides an electric wave axis adjusting apparatus for an on-vehicle radar capable of readily and precisely adjusting an electric wave axis only by making the scanning range and a detection range identical to each other and changing a scanning range, and of adjusting the electric wave axis of an on-vehicle radar without wasting time in order to detect a reflector. In the electric wave axis adjusting apparatus for an on-vehicle radar of the present invention, an on-vehicle radar includes: a radar portion for generating the electric wave; a scanning unit for changing a transmission/reception direction of the electric wave to form within a scanning range, along with having an antenna for transmitting/receiving the electric wave; a signal processing unit for calculating a direction of the reflector based on amplitude of the reflected electric wave; and a scanning range changing unit for changing the angle of the scanning range to an axis side of the vehicle based on the direction of the reflector calculated by the signal processing means to align an electric wave axis of the on-vehicle radar with the axis.
