小波变换是近年发展起来的一个新的数学分支，在地震勘探中已广泛应用。本文将小波变换引入位场信号处理，以便利用小波分解理论将重磁异常进行分解、滤波、重建，达到提取区域异常和局部异常的目的。尤其是在提取微弱信号中发挥作用，利用滤波提高信噪比。
Wavelet transform is a new branch of mathematics developed in recent years and has been widely used in seismic exploration. In this paper, the wavelet transform is introduced into the signal processing of the field, so that the gravity and magnetic anomalies can be decomposed, filtered and reconstructed using the wavelet decomposition theory to achieve the purpose of extracting regional anomalies and local anomalies. Especially in the weak signal extraction play a role, the use of filtering to improve signal to noise ratio.
