    What is Ground Clutter?

    Echoes from surface targets appear in almost all radar images. In the immediate area of the radar, "ground clutter" generally appears within a radius of about 25 miles. This appears as a roughly circular region with echoes that show little spatial continuity and appear nearly stationary. It results from radio energy being reflected back to the radar from outside the central radar beam, from the earth's surface or buildings.

    When in clear air mode (when the radar is in its most sensitive state), the radar may detect echoes from targets on or near the ground. Such targets could include buildings, hills, waves on large bodies of water, migrating birds, swarms of bats and even insects.

    Under highly stable atmospheric conditions (typically on calm, clear nights), the radar beam can be refracted (bent) almost directly into the ground at some distance from the radar, resulting in an area of intense-looking echoes. This anomalous propagation phenomenon (commonly known as AP) is much less common than ground clutter. Certain sites situated at low elevations on coastlines regularly detect sea return, a phenomenon similar to ground clutter except that the echoes come from ocean waves.
