N-indicator

N-display

In radar, a display similar to the K-display, in which the target appears as a pair of vertical deflections or blips from the horizontal time base. The relative amplitude of the vertical deflections indicates direction; target distance is determined by moving an adjustable signal along the baseline until it coincides with the horizontal position of the vertical deflections. The horizontal control is calibrated in distance. Also called an N-scan, N-scope, or N-indicator.
