gound clutter : Radar echoes from tree, 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.  4, record 2, English, - ground%20return

More precisely-defined signal processing was needed, which would not only perform the traditional role of ridding displays of stationary ground clutter, but which would also discriminate between the categories of moving clutter, eg, birds, cars and lorries, fast-moving weather and anomalous propagation returns, while still showing slow-moving aircraft or helicopters.  1, record 4, English, - moving%20clutter
