Page 75 RA83/84/85/93/94/95 Series Chapter 5 Operation Manual Basic Operation Picture resolution The picture resolution depends on the bearing and range discriminations that are solely determined by the antenna horizontal beam width and the transmission pulse length. These factors are defined in the following explanations and illustrations. (1) Bearing discrimination The bearing discrimination is defined as the minimum bearing where two targets of the same distance are displayed as two independent images on the screen.
