GROUND CLUTTER EXTRACTION
The radar processor contains an internal topography database with
elevation data. The radar compares the collected reflectivity data with
the topography 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.
