Quantization
Level''''
CAUTION
Do not change
the
set
quantization
level carelessly.
lf
the
level
deviates
from the
proper
value,
the
ARPA
acquisition and tracking
functions will
deteriorate.
Otherwise, this
may
cause
accidents
to occur.
The
quantization
level determines
the
minimum signal
level
of the
input video to
the ARPA
target detection circuit. ln this
test,
the
value of the
quantization
level
can be set
in a
range of
1 to 63.
lf
the
value is
set
to a
lower
level, weak
target echoes
will
be
inputted
to the ARPA targei
detection circuit, but
much radar
noise will also
be inputted to the circuit
together, and
target
acquisition
and
tracking
may be disabled.
Therefore,
it is important to set a
value
that is
4 or 5 higher
than the detected
noise
level.
