(Example)
Assuming that the
maximum range of the
initial
PM
pattern
is €max
=
18 NM according
to the
INFORMATION LABEL,
and
if lhat
of the cunent
PM
pattern
is
rAmax
=
16 NM, the delerioration
value
is AR
(rmax)
=
SdB,
referring
to
Calibration Curve
ll.
This
means
that the
receiver system
has sensitivity deterioration of approximately
SdB.
