What is ground clutter?

Ground clutter shows up on a radar image as those little spots (or sometimes big blobs!) that make it look like it's raining.

Erica's Answer:

Ground clutter happens when there is no precipitation in the area, and the highly-sensitive radar is basically looking too hard to find precipitation. Instead, it "sees" dust, birds, or other non-precipitation objects in the radar's line of "sight".
