DISPLAY 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 output indicative of the disc rotation angle and range mark position as a distance 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, scaling according to chosen units of measure, and displaying the result with a LED display, the computations being performed by a processor controlled by a permanently programmed memory. The range mark stays on target as the range scale is changed. The amount of movement of the range mark for a given amount of control rotation is independent of range scale.
