Title (EN) TIME SEQUENCED SPECTRAL STITCHING
(FR) RACCORDEMENT SPECTRAL SÉQUENCÉ DANS LE TEMPS
Abstract:
(EN) Methods and systems are disclosed for using a single receiving device, such as a single VSA, to capture and digitize multiple time-domain acquisitions of a repeating signal at different center frequencies, to create a single time-domain waveform having a bandwidth greater than the real-time instantaneous bandwidth of the receiving device. Specifically, one or more signal processing paths may process the multiple digitized acquisitions of the repeating signal, either sequentially or in parallel, such that the processed acquisitions may be aggregated into a representation of one or more repetitions of the repeating signal.
(FR) L'invention concerne des procédés et des systèmes destinés à utiliser un seul dispositif de réception, tel qu'un VSA unique, pour capturer et numériser des acquisitions multiples dans le domaine temporel d'un signal répétitif à des fréquences centrales différentes, pour créer une forme d'onde unique dans le domaine temporel présentant une largeur de bande supérieure à la largeur de bande instantanée en temps réel du dispositif de réception. En particulier, un ou plusieurs trajets de traitement de signal peuvent traiter les acquisitions numérisées multiples du signal répétitif, soit séquentiellement, soit en parallèle, de telle façon que les acquisitions traitées puissent être agrégées dans une représentation d'une ou plusieurs répétitions du signal répétitif.
