Determine whether to use the video process with radar signals for plotting radar trails.
x
When Trails Process is ON , radar trails are never plotted with unwanted waves, but the radar trails
of fast moving targets may not be plotted.
x
When Trails Process is OFF , radar trails may be plotted with unwanted waves, but the radar trails of
fast moving targets are always plotted.
OFF : Disables the Trails Process function.
ON : Enables the Trails Process function.
