Abstract: A programmable fiber optic delay system employs multiple programmable fiber optic delay lines, and switches among the delay lines for inclusion in an overall delay path. Switching among the delay lines is coordinated with the programming of those lines so that only a delay line with a settled delay programm is included in the overall delay path. Each delay line consists of a plurality of fiber optic segments of varying length. The line's delay is programmed by switching in particular segments whose aggregate lengths correspond to a desired delay period. The multiple delay lines are used to simulate target speed and distance for use in testing a radar system. The programming of each individual delay line and the switching between lines is preferably controlled by a computer resident in the target simulator.

Abstract: Un système de ligne à retard programmable en fibre optique utilise plusieurs lignes à retard programmables en fibre optique, et effectue des commutations parmi les lignes à retard afin de les inclure dans une voie de retard globale. La commutation effectuée parmi les lignes à retard est coordonnée avec la programmation de ces lignes de sorte que seule une ligne à retard présentant un programme de retard établi est incluse dans la voie de retard globale. Chaque ligne à retard comprend une multiplicité de segments de fibre optique de longueurs variables. Le retard de la ligne est programmé par la commutation de segments particuliers dont les longueurs totales correspondent à la période de retard requise. Les lignes à retard multiples sont utilisées pour simuler la distance et la vitesse d'une cible afin de mettre à l'épreuve un système de radar. La programmation de chaque ligne à retard individuelle, ainsi que la commutation entre les lignes sont de préférence commandées par un ordinateur résidant dans le simulateur de cible.
