Abstract: Systems and methods for boosting low content of received signals involve a vessel (102) towing port side (205) and starboard side (210) impulsive source arrays. The port side and starboard side impulsive source arrays are selectively actuated for a plurality of sequential shots having different signatures.

Abstract: A method for estimating a time variant signal representing a seismic source obtains seismic data recorded by at least one receiver and generated by the seismic source, the recorded seismic data comprising direct arrivals and derives the time variant signal using an operator that relates the time variant signal to the acquired seismic data, the operator constrained such that the time variant signal is sparse in time.
