Waterfall

Le graphique en bas à gauche donne le waterfall (temps en abscisse, fréquence en ordonnée). Le graphique en haut donne la puissance du signal intégrée en fréquence en fonction du temps. En bas à droite moyenne des spectres sur tous les temps de mesure (fréquence en ordonnée).

L'étendue en temps de la mesure est donnée dans la partie en haut à droite (minimum_time, maximum_time). L'étendue en fréquence déterminée par le nombre de points utilisés par la transformée de Fourier est donnée par fmin et fmax. Les unités utilisées pour la puissance (ou l'énergie reçue dans chaque intervalle de temps) n'ont pas pu être déterminées.

Fit Gaussien

Lorsque l'intensité du signal en fonction du temps suit une loi approximativement Gaussienne, cet outil doit en capturer approximativement les paramètres par ajustement non-linéaire. L'ajustement est réalisé à l'aide de la librairie NLOPT2. Le comportement est indéfini si la loi est quelconque.
