ABSTRACT:
In a digital weather radar display, of the type which displays information on a cathode ray tube in the form of parallel intensity modulated sweep lines and which displays range marks in the form of a plurality of arcs of concentric circles, the positions of the range marks along each of the sweep lines are determined by utilizing a read only memory which stores, for each sweep line, an indication of the distance between range marks and the distance from the beginning of scan of the line to the first range mark.
