In a forward looking radar in which from flying or stationary carriers land or marine surfaces in a forward lying sector region are imaged two-dimensionally, an antenna mounted rigidly on a carrier is made up of a plurality of individual elements preferably in the form of horn antennas arranged rectilinearly adjacent each other and in two rows above each other ? of each individual element and for a predetermined spacing of the individual elements the antenna has an antenna length L = n.?/2. By means of the individual elements in each case a transmitting and subsequently a receiving takes place consecutively from the first to the last of the plurality of individual elements. To implement a digital coupling of the individual elements each said element is evaluated separately digitally and by correlation of a specific predetermined reference function a digital processing is carried out for each angular region.
