摘要： Techniques are disclosed relating to control of seismic sources such as marine vibrators. According to some embodiments, iterative learning control (ILC) systems may be used to control such vibrator including an excitation signal and seismic sources. According to some embodiments, a control unit provides first input signals to the marine vibrator which include an excitation signal and a high-amplitude, low-frequency signal, the latter is operable to decrease friction effects in the marine vibrator. Furthermore local sensor(s) placed in, on, or near a seismic source and/or remote sensors placed in the far-field region to measure the acoustic output of the marine vibrator. The control unit is further configured to generate initial values for a transfer function of the marine vibrator based on the measured acoustic output.

摘要： Vibrateur compact pour émettre des ondes élastiques dans un milieu matériel tel que le sous-sol.
Le vibrateur comporte une plaque de base ou pavillon (3) destiné à être couplée en opération avec une surface de ce milieu, une masse d'inertie (5) et au moins un couple de transducteurs électromécaniques (1, 2) comprenant chacun un ou plusieurs piliers (A, B) réalisés par exemple en un matériau de type piézo-électrique ou magnétostrictif. Les piliers (A) du premier transducteur (1) sont interposés entre le pavillon (3) et une plaque-relais (4). Les piliers (B) du deuxième transducteur sont interposés entre la plaque-relais (4) et la masse d'inertie (5), du même côté de la plaque-relais (4) que les piliers (A) de préférence, de façon que la masse d'inertie (5) soit ramenée au voisinage du pavillon (3), ce qui contribue à la compacité et la stabilité du vibrateur que l'on peut de ce fait utiliser sur des surfaces légèrement en pente. Un générateur d'excitation (6) comportant des moyens de déphasage (7) applique respectivement aux deux transducteurs (A, B) des signaux déphasés les uns par rapport aux autres et modulables en amplitude, de façon que leurs vibrations se conjuguent.
Applications notamment à l'équipement d'une zone d'exploitation d'une zone souterraine en moyens de surveillance sismique périodique ou bien pour réaliser des opérations de prospection sismique.

摘要： A system for geophysical exploration uses a single source (30) which emits signals over multiple octaves. The source is driven by a composite sweep signal having two or more sweeps, one of which covers the lower octave (10) while the other sweeps cover the remainder of the bandwidth. The signals covering the lower portion are reduced in the case of a sweep which varies linearly with time in proportion to the square root of the ratio of the sweep rate of the signals covering the upper end to the sweep rate of the signals covering the lower end. The signals are transmitted simultaneously. Because of the composite sweep the same energy spectrum is transmistted as with a sine wave sweep which extends over the entire frequency band, while reducing the peak power and radiator displacement required at lower frequencies to maintain a flat spectrum. The size of the equipment can be reduced.
