VARIABLE RANGE MARKER ABSTRACT OF THE DISCLOSURE A variable range marker device for use with a PPI radar with digitized video displayed in non-real time. The position of the range marker is initially operator determined by rotation of a knob mechanically linked to an optically encoded disc. Optical sensors produce a digital out- put indicative of the disc rotation angle and range mark position as a dis- tance from the center of the radar display screen. A counter is preset with the digital output at the start of each sweep and decremented once each range cell until a count of zero is reached at which time an unblanking pulse is produced. A numeric display of range is produced by dividing the number of range cells to the range mark by the range setting and displaying the result with a three digit LED display.
