Backup Cursor
StructureScan2D includes the backup cursor
function. This allows you to back the antenna
over the line you just surveyed and get an on-
screen cursor that will help you relate the
location of targets in the data back to the slab.
The backup line in the data is the location of the
midpoint of the antenna and shows the distance
from the start of the line.
