Abstract:
1. A seismic data processing method, comprising: measuring reaction mass acceleration data of a source of seismic energy with an accelerometer; measuring baseplate acceleration data of the source with an accelerometer; measuring seismic data with one or more seismic sensors responsive to the seismic energy of the source; deriving, via a data processing system comprising one or more processing units, variables for a ground model by analyzing a frequency response relating the reaction mass acceleration data and the baseplate acceleration data as input and output relative to one another; storing the ground model in memory operatively coupled to the data processing system; filtering via the data processing system a source signal indicative of operation of the source by using the ground model with the derived variables; and making the filtered source signal available for processing with the seismic data of the one or more seismic sensors via the data processing system; wherein deriving the variables for the ground model comprises modeling a baseplate system of the source in the ground model with a first transform function based on a mass value M wherein the first transform function comprises:
