Abstract
The present invention relates to a method for determining the angular aperture corresponding to the extent in a plane of an object seen by a radar antenna, the object being situated at a given distance from the radar antenna. Echoes are measured in directions of the plane, where θis a variable angle corresponding to directions of the plane and Δθ is a given angular aperture. The pairwise differences are calculated between the echo measurements taken in the directions The slope is determined at a value θof a function e of θinterpolated between the calculated differences, the angular aperture which corresponds to the extent of the object at the given distance being deduced from the slope. The invention has an application in meteorological radar.
