摘　　要：信号处理水平的发展,使提高复杂信号的分解清晰度问题得以实现。以煤矿随钻地震信号为研究对象,提出了小波变换域互相关算法在处理地震信号降噪中的应用。通过数值模拟分析及实验分析,验证了小波变换域互相关算法相对传统时域互相关算法的优越性。With the development of signal processing technology, improve the decomposition of complex signal is improved to achieve clarity. Taking the coal mine drilling seismic signal as the research object, presents the application of wavelet transform domain cross-correlation algorithm in processing of seismic signal denoising is proposed. Through the analysis of numerical simulation analysis and experimental verification, wavelet transform domain cross-correlation algorithm superiority compared with the traditional time domain cross-correlation algorithm.
