Abstract

Procédé et dispositif de mesure de hauteur d’un aéronef en vol par rapport à au moins un point du sol L’invention concerne un procédé et un dispositif de mesure de hauteur d’un aéronef en vol par rapport à au moins un point du sol, ledit aéronef étant porteur d’un système de radar comportant au moins une antenne directionnelle, adapté à émettre au moins un signal radiofréquence selon un axe de visée de direction pilotable. Le procédé comporte des étapes de: -commande (30) d’émission d’un signal radiofréquence selon un axe de visée, -calcul (32) de puissances reçues en fonction d’une distance radiale sur deux voies de réception comportant une première voie dite voie somme et une deuxième voie dite voie écart en élévation, -calcul (34) de valeurs d’écartométrie angulaire en site en fonction de la distance radiale formant une courbe d’écartométrie angulaire, -détermination (38, 39) d’un estimateur de la distance radiale de l’aéronef par rapport au point du sol intercepté par l’axe de visée en fonction d’au moins un passage à zéro de l’écartométrie angulaire dans une zone choisie de la courbe d’écartométrie angulaire, -calcul (40) d’une hauteur de l’aéronef par rapport audit point du sol en fonction de l’estimateur de la distance radiale et de l’angle en site de l’axe de visée.
