Effet fantôme se manifestant par des formes linéaires brillantes dont la distance en portée est à peu près constante. 3, record 1, French, - ambigu%C3%AFt%C3%A9%20sur%20le%20nadir

Le signal reçu du nadir est une forte réflexion spéculaire de cibles situées à très faible distance en portée. Il en résulte sur l'image des tons très brillants. À cause de la compression des impulsions, le signal puissant se restreint à un petit nombre de pixels en portée. Sur les images à faisceau unique, les ambiguïtés de nadir peuvent apparaître près de la bordure des images en mode large, obtenues en temps réel ou au centre des images. Dans cette opération, les opportunités d'attraper une petite caractéristique spécifique digne d'intérêt sont rares pour ne pas dire inexistantes. 2, record 1, French, - ambigu%C3%AFt%C3%A9%20sur%20le%20nadir
