A method for separating composite data from simultaneous sources containing data responses to at least two sources, apparatus for acquiring and separating simultaneous source data by a diverse frequency filter, where composite simultaneous source data contains responses to at least two sources, and system data processing to separate simultaneous source composite data by diverse frequency filtering, where simultaneous source composite data contains responses to at least two sources

摘要

Generating an image of an interior of the Earth from a seismic survey using multiple sources. The multiple sources may be fired simultaneously and the data received by seismic sensors in the seismic survey may be decomposed so that seismic data generated by each of the multiple sources may be determined. Decomposing of the received data may be performed using frequency diverse basis functions and converting the data separation problem into an optimization problem, which can be a one-norm or zero-norm optimization problem in frequency-space domain. The decomposed data may be used to generate the image of the Earth's interior.
