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 function of clutter control in radar?
The “anti- Sea Clutter” control reduces sensitivity near the center, in order to remove the clutter, but does not affect long distance detection. As you increase the “anti-Sea Clutter” control, the gain suppression moves outwards from the center of the display.
How do you minimize clutter in a radar system?
The results show radar clutter can be mitigated either by reducing the ground area illuminated by the antenna, in the case of surface clutter, or by reducing the pulse duration, in the case of volume clutter.
