The distributed fiber optic system based on phase-sensitive optical-time-domain reflectometry (Φ -OTDR) has attracted extensive interest in the field of perimeter security. However, noise caused by environmental factors signal processing is a great difficulty due to complexity and variability natural environment. In this paper, an improved wavelet de-noising method classification error training data proposed solve filtering thresholds selection. By maximizing true positive rates under...
The technology of pattern recognition for vibration events based on the phase-sensitive optical time domain reflectometer (Φ-OTDR) has been significantly improved, thanks to plenty valuable research in recent years. However, it remains challenging develop an efficient algorithm with computing resources that are simpler achieve at lower cost. To best our knowledge, this paper, first time, analyzes superiority using graphics processing unit (GPU) parallel improve time-consuming performance...
