Patent

CA 2649887

There is disclosed a method for filtering sea clutter in a radar echo using a hydrographic model. The method comprises the following steps : determination of parameter values of the hydrographic model using the radar echo; estimation of the sea clutter corresponding to the sea surface as deduced from the hydrographic model; filtering of the estimated sea clutter from the radar echo. Application : radar detection.

La présente invention concerne un procédé de filtration d'effet de mer dans un écho radar au moyen d'un modèle hydrographique. Ce procédé consiste à déterminer des valeurs de paramètre du modèle hydrographique au moyen de l'écho radar, à évaluer l'effet de mer correspondant à la surface de la mer tel que déduit à partir du modèle hydrographique, puis à filtrer l'effet de mer évalué dans l'écho radar. Cette invention s'applique à la détection par radar.
