Title (EN) METHOD AND APPARATUS FOR RADAR IMAGING
(FR) PROCÉDÉ ET APPAREIL DE GÉNÉRATION D'IMAGE RADAR
Abstract:
(EN) A method and apparatus for generating a radar image. The method has the steps of A) Generating radar measurements using a radar signal, B) Performing interferometry on groups of the radar measurements to generate Skyline images, where the number of frequencies and/or number of measurement locations is sufficient to resolve scatterer location ambiguity, and C) Generating an image by evaluating variations of values in corresponding locations of multiple Skyline images based on non-parallel baselines, to identify a scatterer intensity at various positions.
(FR) L'invention concerne un procédé et un appareil de génération d'image radar. Le procédé consiste à : a) générer des mesures radar à l'aide d'un signal radar; b) effectuer une interférométrie sur des groupes des mesures radar afin de générer des images de ligne d'horizon, le nombre de fréquences et/ou le nombre d'emplacements de mesure étant suffisants pour résoudre une ambiguïté d'emplacement de diffuseur; et c) générer une image par évaluation de variations de valeurs dans des emplacements correspondants de multiples images de ligne d'horizon, en fonction de lignes de base non parallèles, pour identifier une intensité de diffuseur à diverses positions.
