A B S T R A C T The invention is for a method of seismic exploration involving the generation of a nonlinear signal of predetermined shape at the output of a sweep generator which comprises the steps of dividing the sweep time of the output signal into a plurality of preselected time intervals, calculating the rate of change of the frequency of the output signal for each time interval to realize the predetermined shape based on the range of the sweep, the sweep time, the starting frequency and the predetermined shape, and using each value in the calculating step to change the rate of change of frequency of the sweep signal, and the invention includes the apparatus specifically adapted to carry out the inventive method.
