In-solid Acoustic Sources Extraction Using a Multi-sensor Architecture

Abstract

This paper presents a novel signal feature extraction method based on Location Pattern Matching (LPM) for improving the reliability of pattern matching of received acoustic signals by using multi-sensor architecture. The proposed solution is to solve the reliability problem of signal matching by extracting specific features from the signal that is only associated with the source location not the source information with multi-sensor layout. Experiments showed that this method can increase the tolerance of LPM on various types of impacts, thus the matching accuracy.
