Abstract
The disclosure relates to methods and devices for adjusting and setting the alignment of the radio axis of a radar installed on a vehicle with respect to a determined direction. The method, in making use of an adjustment and setting stand comprising a goniometer-responder, consists: in acquiring the angles &agr; and &bgr;, &agr; a being the azimuthal angle at which the radar perceives the goniometer-responder and &bgr; being the angle between the determined direction and the axis of the stand; determining the azimuth &ggr; of the radar by means of the goniometer-responder when the radar, configured in test mode, sends out a continuous frequency; equalizing the azimuth &ggr; with the angle &bgr; by translating the goniometer-responder along its axis of motion; nullifying the angle of azimuth &agr; by actuating the means to adjust the radar in azimuth. The device includes a goniometer-responder used to locate the radar in azimuth and in elevation when the radar is in test mode and sends out a continuous frequency. Application: especially to the adjustment and setting of the alignment of the radio axis of a radar installed on a vehicle with respect to the thrust axis of the vehicle.
