What is clutter in signal processing?
Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, and can cause serious performance issues with radar systems.
What is volume clutter?
There are three types of clutter, surface, volume, and point clutter. Surface clutter is returns from the ground and sea. Volume clutter examples are rain, snow, and hail. Finally, point clutter are when birds or tall buildings obstruct the radar beam. Ground clutter can be caused by an inversion.
What is main beam clutter?
Main lobe clutter occurs when there are undesirable returns in the main lobe or within the radar beamwidth.
What is point clutter?
Point Clutter – Birds, windmills and individual tall buildings are typical point clutter and are not extended in nature. Moving point clutter is sometimes described as angels. Birds and insects produce clutter, which can be very difficult to remove because the characteristics are very much like aircraft.
