1. A method for processing a radar image, the method comprising:

  • using a radar, generating a radar image of an area of terrain, the radar image deriving from radar observations taken along a plurality of azimuth angles;

    performing a background extraction process on the radar image to extract a background image comprising extracted radar observations, the background extraction process comprising estimating a range spread of a radar echo from the surface of the terrain as function of the azimuth angle and a tilt of the radar relative to the surface of the terrain;

    fitting a model to the extracted radar observations along a particular azimuth angle;

    determining a value of a parameter indicative of the goodness of fit between the model and the extracted radar observations along the particular azimuth angle; and

    determining a classification depending on the value of the parameter for that azimuth angle.
