ABSTRACT:
The invention is a method of shaping the spectrum of a seismic source signature. Energy is concentrated in the range below a selected frequency and attenuated in the range above the selected frequency by activating a plurality of sources asynchronously within a time window of selected duration. In a preferred embodiment, the frequency spectrum is smoothed by firing a second plurality of sources within a second time window having a time delay from the first time window equal to substantially the time between the initial firing of a source and the first positive zero-crossing of the signature.
