Title
(EN) SYSTEMS AND METHODS FOR INTERPOLATION IN SYSTEMS WITH NON-LINEAR QUANTIZATION
(FR) SYSTÈMES ET PROCÉDÉS D'INTERPOLATION DANS DES SYSTÈMES À QUANTIFICATION NON LINÉAIRE
Abstract
(EN) Various aspects and examples are directed to methods and systems for interpolation in systems that execute non-linear quantization routines. Particular aspects of the methods described herein include a method of detecting a Radar Cross Section (RCS) and a method of detecting patient injuries. In one example, a method of detecting RCS includes receiving a sequence of samples at a re-visit rate of a radar antenna, the sequence of samples being based on electromagnetic energy reflected from a target, interpolating a model curve to the sequence of samples, where each sample of the sequence of samples geometrically increases in value relative to a previous sample of the sequence of samples, comparing the model curve to a calibrated curve and determining a shift between the model curve and the calibrated curve based on the comparison, and detecting a RCS based on the shift between the model curve and the calibrated curve.
(FR) Divers aspects et exemples de l'invention concernent des procédés et des systèmes d'interpolation dans des systèmes qui exécutent des sous-programmes à quantification non linéaire. Des aspects particuliers de l'invention concernent un procédé permettant de détecter une surface équivalente radar (SER), ainsi qu'un procédé permettant de détecter les lésions d'un patient. Dans un exemple, un procédé de détection de SER consiste à : recevoir une séquence d'échantillons selon un taux de visite d'une antenne radar, la séquence d'échantillons étant basée sur l'énergie électromagnétique réfléchie par une cible; interpoler une courbe modèle avec la séquence d'échantillons, chaque échantillon de la séquence d'échantillons augmentant de valeur de façon géométrique par rapport à un échantillon précédent de la séquence d'échantillons; comparer la courbe modèle avec une courbe étalonnée et déterminer un décalage entre la courbe modèle et la courbe étalonnée d'après la comparaison; et détecter une SER d'après le décalage entre la courbe de modèle et la courbe étalonnée.
