Abstract:

For the high-precision signal requirements of vibrator in the seismic exploration,this paper proposes a solution to implement the linear sine sweep DSP-based signal source,including the hardware and software design.The solution not only improves the sweep signal generator's accuracy and waveform stability and reduces the waveform distortion,but also has the advantages of simple operation,reliable and stable working performance.
