Forms of visual representation are shown and illustrated on the basic screen (panoramic representation and setting, alarms) and on the auxiliary screen (type A, B and special). Special forms of visual representation are mainly used in detecting objects in difficult hydrological conditions and when classifying objects. Several types of visual representations are shown, including a historical data example, multiplied type A representation in multiple beams and two types of quasi-spatial displays.
