Abstract
The present disclosure includes a method for stabilizing controlled seismic signals based on uncontrolled seismic signals. The method includes calculating reconstructed signals associated with a first receiver. Each reconstructed signal is based on uncontrolled signals recorded by a respective pair of receivers that includes the first receiver and a respective second receiver. The method also includes calculating signal variations. Each signal variation is associated with a respective pair of receivers and based on a difference between the reconstructed signal associated with the respective pair of receivers and a reference associated with the respective pair of receivers. The method also includes calculating a stabilization factor for the first receiver based on the first signal variations. The method also includes modifying controlled seismic signals recorded by the first receiver by applying the stabilization factor to the controlled seismic signals. The present disclosure may also include associated systems and apparatuses.
