[II] Quantization Level Adjustment (Video Level)
Use the target tracking function (TT) to adjust the level of the signal to be recognized as a target. If a
small value is set, even weak target signals will be input to the target detection circuit of the target tracking
function. However, many unnecessary signals are also input, which may cause unstable target acquisition
or tracking. It is important to set a value four or five greater than the value with which unnecessary signals
are detected.
The quantization level is adjusted to an optimal value, so do not change it carelessly.
Do not change the quantization level settings unless
absolutely necessary. If set at an inappropriate value, the
target acquisition or target tracking function deteriorates,
and this may lead to accidents.
