摘　　要：脉冲探地雷达回波信号是典型的非平稳、非线性信号。本文通过连续小波变换，对地下圆柱目标实测结果进行分析，得到了目标冲击响应的典型波形特征。分析结果证明，这种方法可以有效地用于目标检测。Signals of a pulse echo mode ground penetrating radar (GPR) possess typical nonstationary and nonlinear properties. In this paper, continuous wavelet transforms are adapted to analyze the field measurement data of buried cylinders and then the waveform characteristics of target impulse response are detected. The results show that the technique can be effectively applied to such problems in GPR signal processing as detection and time delay estimation.
