Abstract
Reception antenna elements are formed so that the reception beam axis in the vertical direction of at least one reception antenna element of a transmission/reception unit is displaced from the reception beam axes of the other antenna elements. Therefore, the amplitude (intensity) of the reception signals of the reception antennas which are caused by a target is different from the amplitude (intensity) of the reception signal of the reception antenna element, and the amplitude difference is varied depending on the orientations of the reception beam axes in the vertical direction of the reception antenna elements. Accordingly, the amplitude difference when the reception beam axes of the reception antenna elements are correctly oriented to a desired direction is measured in advance, and the amplitude difference thus measured is set as a target amplitude difference, whereby the mount angle of the transmission/reception unit can be easily and accurately adjusted.
