A clutter fence is a device used with some radar systems to limit unwanted reflections from nearby objects reaching the receiver.
These reflections could generate false or confusing data (clutter), obfuscating objects the radar is intended to detect.
A clutter fence is normally constructed from conventional metal fencing material.
It may serve a secondary role by protecting crews on the ground from the intense microwave emission of some very high-powered radar transmitters.
