小波变换在地质雷达信号处理中的应用

Application of Wavelet Transform in GPR Signal Processing

地质雷达信号处理的关键是去除噪声提取有用信息。小波变换是近年发展起来的信号处理手段,通过设定不同的尺度参数,来提取不同空间域的信号。将小波变换用于雷达信号处理中,阐述了小波变换用于信号去噪的基本原理,实际应用结果表明,去噪效果良好,提高了信噪比。

The key of signal processing of GPR is to remove noise and pick up useful information. As a new method of signal processing, wavelet transform refines different spatial domain signal, setting up variant scale parameters. This paper applies the wavelet transform to GPR signal processing and introduces the basic concepts of wavelet transform. The result of application demonstrates that wavelet transform de-noising effect is satisfied and improved signal-noise-ratio.
