摘要

探地雷达在无损检测中得到了广泛的应用,但其解释却很困难。本文提出了基于短时傅里叶变换(STFT)的目标识别算法,对信号进行时频域分析得到滚动频谱,然后利用Otsu算法计算阈值,将其转换为二进制数,从而利用标记连通分量算法对目标进行识别。实验表明,该算法能有效地识别探地雷达信号中的目标,并表明STFT能极大地提高目标识别能力。

Study of object recognition with GPR based on STFT
Ground Penetrating Radar has been widely used in nondestructive testing, but its interpretation is difficult. This text put forward to the algorithm of recognizing object based on short-time Fourier transform (STFT), the signal is analyzed in time-frequency domain to obtain the rolling spectrum, and then calculated threshold using Otsu arithmetic to convert to binary number, so that the object can be recognized using the algorithm of label connected components. The experiment expressed this algorithm can recognize the object of the GPR signal effectively, and indicated that STFT can improve object recognition greatly.
