Method for processing measured vertical profiles of the power of the echoes returned following a transmission of radar signals

A computer processor implemented method for processing measured vertical profiles of the power of the echoes returned following a transmission of radar signals, each measured vertical profile being a function of the sweep angle of the radar beam and associated with a given pointing angle/distance box pair of the radar beam, the method comprising:

• an obtaining of a stored synthetic vertical profile of the power of the echoes returned by the ground only, and for each measured vertical profile:
• a superposition of the synthetic vertical profile on the measured vertical profile in question, for various values of the sweep angle,
• a calculation of the error that exists between the measured vertical profile and the synthetic vertical profile, for each sweep angle value in question, and
• an exclusion, from the measured vertical profile, of the values for which the calculated error is less than a given threshold, called values to be excluded, in order to generate a resultant vertical profile with no ground echoes, wherein
• the obtaining, superposition, calculation, and exclusion are performed by the computer processor, and
• the stored synthetic vertical profile corresponds to a shape of an antenna diagram of a radar antenna.
