摘要
Abstract
Aiming at the low SNR in magnetic anomaly detection ,a new algorithm was proposed using FIR low‐pass filter integrated into orthonormalized functions decomposition algorithm .Firstly the FIR low‐pass filter was constructed to filter the high frequency noise in the raw signal .Then the disposed signal was decomposed by orthonormalized functions de‐composition algorithm to increase SNR .The simulation result demonstrated the method can increase the detection ability of magnetic object and possesse engineering application value .关键词
