摘要： Methods and systems for detecting a plume of a first fluid in a second fluid using an acoustic wave are provided, where the first fluid has a different acoustic index of refraction than the second fluid. A horizontal array having a plurality of receiving elements receives an acoustic signal propagated through the second fluid and at least one refracted signal refracted by the first fluid. The acoustic signal and the at least one refracted signal form a received signal. An interference pattern is detected from the received signal over the plurality of receiving elements. The interference pattern is due to interference between the acoustic signal and the at least one refracted signal. A horizontal angle of refraction is determined between the acoustic signal and the at least one refracted signal from the interference pattern. The horizontal angle of refraction is indicative of a physical characteristic of the first fluid.

摘要： The invention relates to a method and system for determining a parameter representing an acoustic property of a material. The method comprises: generating an acoustic pressure wave in said material originating from a localized position; placing a plurality of acoustic receivers (6, 7) at mutually differing distances from the acoustic source (3); transforming a plurality of measured acoustic signals to represent field values in a common computational point; computing a signal representing a measure of overlap between said transformed plurality of acoustic signals as a function of said numerical estimates of said acoustic property parameter and deriving said acoustic property parameter from said overlap signal. Since the invention uses acoustic sources that are well localized in the material, the velocity calculations are simple and the geometry of the acoustic receivers in relation to the acoustic source can be exactly taken into account.
