Abstract
Procédé de mesure de l'altitude d'une cible évoluant à des sites très bas par la détermination, à différentes fréquences de fonctionnement d'un radar monopulse, de l'écanométrie instantanée de la cible. Evaluation, à ces fréquences, de la composante en quadrature du signal différence, détermination des valeurs moyennes de l'écartométrie instantanée et de la composante en quadrature pour un certain nombre d'échantillon de fréquences et recherche d'un extrémum de ladite valeur moyenne de la composante en quadrature, pour valider la valeur de l'écartométrie moyenne correspondante. Application à la poursuite en site de cible évoluant à site très bas.
