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.

What is meant by radar clutter?
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 causes radar clutter?
Typical sources of clutter are birds, trees, bodies of water, and weather (rain, snow, fog). Clutter can cause false alarms in a radar system and limit the ability to process true target detections, posing a significant threat to warfighters.
What is the difference between sea clutter and rain clutter?
Sea clutter is produced by reflections from the sea. It is affected by wave height, wind direction and the antenna height above sea level. It may extend outward as far as 5 nautical miles. Rain clutter is produced by reflections from rain, snow or fog.
What are the three types of radar?
Monostatic, Bistatic and Multistatic
In a bistatic radar, the transmitter and receiver are separated by a distance similar to the expected target distance (Figure 2). A system that includes multiple spatially distributed monostatic or bistatic radar elements covering a common area is called multistatic radar.
