Example: Preventing Target Masking with Enhanced Iron Resolution
In the illustration above, the ACE 350 is operating in RELICS Mode, with
two pixels of iron discriminated. The nail seen in Illustration 1 (on page 22)
registers above the third pixel. These ferrous targets can be eliminated from
detection by using the Accept/Reject pushbutton (/X) to turn off the third
pixel from the left.
In Illustration 2, one of the same iron nails is laying above a good coin target.
Since three pixels of ferrous have been notched out, the nail by itself would
not be detected; however, the two objects have a combined conductivity of
four pixels.
Therefore, the good target is detected due to the combined conductivity
being higher than that of the discriminated target (nail) alone.
