摘要
利用复信号分析可求得表征探地雷达信号特征的多个参量，从而可对雷达信号进行深入的分析和研究．然而，该方法对噪声特别敏感．为此，作者引入小波变换，对分析过程进行了改进．实际处理效果表明：小波变换的引入很好地克服了复信号分析缺点．
Complex signal analysis is different from Fourier analysis. Many parameters to characterize the signal can be got by complex signal analysis so that further study of the signal can be completed. However, complex signal analysis will amplify the noise in the data. To solve this problem wavelet transform is introduced. The field example proves that complex signal analysis based on wavelet transform plays an important role in explanation of GPR record.
