A.4 Echo processing
Auto False Echo Suppression Range
Auto False Echo Suppression Range specifies the range within which the learned TVT is
applied. Default TVT is applied over the remainder of the range.
The learned TVT screens out the false echoes caused by obstructions. The default TVT
allows the material echo to rise above it.
Auto False Echo Suppression Range must be set to a distance shorter than the distance to
the material level when the environment was learned, to avoid the material echo being
screened out.
