基于DSP的可控震源扫频信号的实现

Implementation of Sweep Signal for Vibrator Based on DSP

针对地震勘探中可控震源信号的高精度需求,提出了一种基于DSP线性扫频信号源的系统软硬件设计方案。该方法提高了扫频信号源的精度和波形稳定性,减小了波形的失真,且系统工作稳定可靠,操作简单实用,具有良好的应用前景。

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.
