1. A method of performing a seismic sweep using a seismic source, comprising:
forming a composite force profile of the seismic source by combining at least two force profiles, the at least two force profiles comprising at least two of:
a force profile using one or more steady state sweeps,a force profile using one or more transient force sweeps,a force profile using one or more transient frequency sweeps, anda force profile using one or more transient force and frequency sweeps; constructing a target seismic frequency sweep using the composite force profile; and operating the seismic source using the constructed target frequency seismic sweep.
