Anti-Clutter Sea Control
For optimum range SART detection this control should be set to the minimum. Care
should be exercised as targets in sea clutter may be obscured. Some radar sets
have automatic/manual anti-clutter sea control facilities in which case the operator
should switch to manual.
Anti-Clutter Rain Control
This should not be used when trying to detect SARTs as the SART responses may
be removed by this control. Some sets have automatic/manual anti-clutter rain
control facilities in which case the operator should switch to manual.
