Patent ID: 7714766

Claim:
Method of processing a radar image from a radar antenna, the radar image comprising a plurality of pixels having an associated reflectivity value, the method comprising the steps of: pre-processing the radar image by a first predetermined procedure, to produce a first pre-processed image comprising a plurality of first pixels; pre-processing the radar image by a second predetermined procedure, to produce a second pre-processed image comprising a plurality of second pixels, the second predetermined procedure comprising the steps of: extracting an object from the radar image, to produce an extracted object; calculating an extent and a position of the extracted object by use of an angular aperture between two predetermined signals; and determining an associated reflectivity value for the second pixels of the extracted object; for each extracted object, replacing each of the plurality of the first pixels of the first pre-processed image with the corresponding second pixel of the second pre-processed image, if the reflectivity value associated with the second pixel is greater than the reflectivity value of the first pixel, wherein the replaced pixels correspond to zones situated at a distance greater than a predetermined threshold from the radar antenna.
