K-scan

K-display

In radar, a modified A-display, in which a target appears as a pair of vertical deflections or blips instead of a single deflection. When the radar antenna is correctly pointed at the target in azimuth, the blips are of equal height. When pointed incorrectly, the difference in the blip height is an indication of the direction and the magnitude of the azimuth pointing error. Also called a K-scan, K-scope, or K-indicator. See also A-scope.
