Seismic signal is widely used in ground target classification due to its inherent characteristics. However, its propagation is highly dependent on local underlying geology. It means that nearly every one geographical environment requires a unique classifier. To resolve the problem, this paper presents a robust feature extraction method Log-Sigmoid Frequency(More)
This paper introduces a novel AE intelligent sensor networks system. The system is composed of three parts: the wide band AE sensors, the real-time signal acquisition and processing nodes and an intelligent information terminal. This system acquires AE events from the reinforced concrete structure through its wide band AE sensors, and then extracts the AE(More)
