摘要

针对传统的OBF分解算法在非高斯噪声下检测性能较差的问题,提出了基于小波域OBF分解的磁异常信号检测算法。首先对含噪信号进行小波分解,提取最后一层的低频分量;再对低频分量作OBF分解,提取能量特征信号进行门限检测。试验结果表明,该算法显著增强了非高斯噪声下微弱磁异常信号的检测效果。

Abstract

Considering the bad effect of OBF decomposition algorithm in non-Gaussian noise, a detection algorithm for magnetic anomaly signal based on OBF decomposition in wavelet domain was proposed. First, the raw signal was decomposed by wavelet transform, and the low frequency components in last level were taken out. Then, the low frequency components were decomposed by OBF and the energy signal was taken out for threshold detection. The results of experiment show that the algorithm improves the effect for detecting weak magnetic anomaly signal in non-Gaussian noise environment.

Key words： magnetic anomaly detection; non-Gaussian noise; wavelet transform; OBF decomposition
