发明名称 HIGH-FREQUENCY CONTENT BOOST FOR VIBRATORY SEISMIC SOURCE AND METHOD
摘要 Computer software, controller and method for generating a desired pilot signal for driving a vibratory source. The method includes steps for selecting a pilot target amplitude spectrum for the vibratory source; determining an initial pilot signal that matches the pilot target amplitude spectrum; associating the initial pilot signal with first and second frequency bands, the second frequency band including a high-frequency end of a range of the vibratory source; band-passing a first part of the initial pilot signal associated with the first frequency band with a first band-pass configuration; band-passing a second part of the initial pilot signal associated with the second frequency band with a second band-pass configuration; level compressing the first and second parts of the initial pilot signal; recombining the first and second parts of the initial pilot signal to form a recombined pilot signal; and processing the recombined pilot signal to obtain the desired pilot signal.
