Abstract
A method for processing signals of an airborne radar includes a correction of the erroneous angle of pointing of the radar beam, comprising an evaluation of the error in the pointing angle for a constant height of the aerial transporter. For a given angle of scan, the method carries out at least two series of measurements of the power of the echoes returned following the emission of radar signals, each series being associated with a given distance-bin, the measurements being dependent on the angle of pointing of the radar antenna, formulates a vertical profile of the power of the echoes returned for each series of measurements, and then on the basis of each vertical profile, measures the pointing angle corresponding to a power of the echoes returned by the ground alone, and calculates the error in the pointing angle on the basis of the measured pointing angles.
