Electric wave axis adjusting apparatus for radar mounted on vehicle
First Claim
1. An electric wave axis adjusting apparatus for an on-vehicle radar, comprising:
- a reflector disposed in a predetermined position relative to a vehicle; and
an on-vehicle radar for transmitting an electric wave toward the reflector and receiving an electric wave reflected by the reflector, to thereby detect the reflector, the on-vehicle radar comprising;
a radar portion for generating the electric wave;
scanning means 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;
signal processing means for calculating a direction of the reflector based on amplitude of the reflected electric wave; and
scanning range changing means 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.

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.
