Views are no longer limited to the single diagonal slice that is inherent to
conventional radars. The standard horizontal view of the radar
represents a weather envelope based on flight path slope, and
corrected for the curvature of the earth. Horizontal views are generated
independently for each side of the cockpit.


The radar processor contains an internal terrain database with elevation
data. The radar compares the collected reflectivity data with the terrain
database. Reflectivity data that correlates to terrain data is considered
ground-clutter, and is suppressed from the weather images. However,
the data that is suppressed from the weather images is retained for
display when the radar's MAP Mode is selected.
