Title (EN) METHOD AND APPARATUS FOR GENERATING A COMPOSITE AND PULSE SHAPED FREQUENCY SWEEP SIGNAL
(FR) METHOD ET APPAREIL POUR PRODUIRE UN SIGNAL DE BALAYAGE DE FREQUENCE COMPOSITE ET A IMPULSIONS
Abstract:
(EN) Method for generating a composite and pulse shaped frequency signal. The signal is built up by taking as a basis an elementary signal block (B2) comprising a small number of frequency sweep signals and having a limited extent as to period time (Ts) and period bandwith (Bs). An in the principle infinite number of elementary signal blocks (B2) are assembled with coinciding frequency and phase at the transitions between the elementary blocks, so that there is generated a sum of continuous frequency sweep signals by repeating of the elementary block (B2) both in time and frequency.
(FR) Méthode de production d'un signal de fréquence composite et à impulsions. Ledit signal est établi en prenant pour base un bloc signal élémentaire (B2) comprenant un faible nombre de signaux de balayage de fréquence et ayant une portée limitée en période temps (Ts) et en période-largeur de bande (Bs). Un nombre, en principe infini, de blocs de signaux élémentaires (B2) sont assemblés avec une fréquence et une phase coïncidantes aux emplacements de transition entre les blocs élémentaires, de manière à créer une somme de signaux continus de balayage de fréquence par la répétition du bloc élémentaire (B2), à la fois en temps et en fréquence.
