9. Granularity
Unlike mechanical scanning, and due to the quantization of the commands, the beam of an electronically scanned antenna does not move continuously, but advances in jumps, if a continuous variation is commanded.
For a position command in a given direction, the beam points in this direction with a standard deviation error σ u and σ v 8 .
In the case of continuous variation, the...
