The pattern of radar echoes from fixed ground targets near the radar. This type of clutter tends to hide or confuse the echoes from detecting precipitation areas.
Unwanted echoes, from surrounding land masses, that appear on a radar indicator.
A pattern of radar echoes from fixed ground targets (buildings, hills, etc.) near the radar. Ground clutter may hide or confuse precipitation echoes near the radar antenna. It is usually more noticeable at night when the radar beam is encountering superrefractive conditions.
a pattern of radar echoes from fixed ground targets (buildings, hills, etc.) near the radar. This contamination is processed into the NEXRAD base products ( base reflectivity, base velocity, and spectrum width) and affects all derived products. Ground clutter is most prevalent close to the radar at the lowest elevation slices. Ground clutter is always present around the radar and is not the same as anomalous propagation (AP), which occurs during certain atmospheric conditions.
Radar echoes from trees, buildings, or other objects on the ground. Such echoes may be caused by the reflection of energy back to the radar in the main lobe or sidelobes of the antenna pattern and, in weather radar applications, interfere with the meteorological echoes at the same range.
A pattern of radar echoes reflecting off fixed ground targets such as buildings or hills near the radar. This may hide or confuse the proper return echo signifying actual precipitation.
