In radar, a display in which a target appears as a complete circle when the radar antenna is pointed correctly at it and in which the radius of the circle is proportional to the target distance. When not correctly pointing at the target, the circle reduces to a segment of a circle, with the segment length inversely proportional to the magnitude of the pointing error and its angular position reciprocal to the direction of the pointing error. In its strictest form, the target altitude and the direction are not indicated on this type of display. The display finds its use in surface-to-air weapons firing radars. Also called an I-scan, I-scope, or I-indicator.

STOCKHOLM & NUREMBERG, Germany -- New I-scope probe facilitates low-power development by adding in-circuit power measurements
By adding I-scope, developers can gain knowledge of the power consumed by individual modules, detect if design flaws in the code are causing unnecessary power consumption and possibly extend battery lifetime.
At any designated point on the target board, I-scope can measure current and voltage with 12-bit resolution at a sampling rate of up to 200 kHz.
