Clutter
Unwanted radar returns from the environment — ground, sea, weather, buildings, or birds — that can mask real targets. Small, slow drones are hard to detect precisely because their returns sit close to the clutter floor.

Why it matters
Clutter is the practical reason small, slow drones are hard to see on radar: the return you want is buried in returns you do not, so clutter rejection often decides whether a sensor is useful at all.
