Abstract

La mesure d'écartométrie finale d'une cible est calculée à partir d'un ensemble d'échantillons de mesures d'écartométrie monopulse de signaux rétrodiffusés par ladite cible, la mesure d'écartométrie finale étant obtenue en effectuant une moyenne pondérée desdits échantillons de mesure dont les coefficients de pondération décroissent en fonction de l'écart de l'échantillon à pondérer par rapport à la médiane des mesures d'écartométrie.
