In each case the position of the entry
point of search unit corresponding to
maximum echo height is marked on
the block. The search unit is then
moved forward and backward so
that the target is swept by the beam,
the extremes of displacement being
reached when the position of the
entry point of search unit
corresponds to a fall of 20 dB from
maximum Echo Height ( See Fig. 4,
a, b, c & d ).
When the entry point in its forward
position, the edge of the target hole
intercepts the lower on rear
boundary of the 20 dB reference
surface, and vise versa when the
search unit is in the hid most
position. The forward and backward
position on the entry point of search
unit are also marked on the block.
Similar measurements made at each
target hole are used to construct a
diagram of the beam profile, figures
4a, b, and c illustrate the plotting
sequence.
b. The reading Y ( forward position ) is
laid off behind the beam axis and the
backward shift X in front of it. Figure
4d shows the complete profile with
target.
Pada setiap kasus posisi titik point
