Paper Abstract

Based on phase-sensitive optical time domain reflectometer (φ-OTDR) and phase-generated carrier (PGC) algorithm, a real-time DAS system is built. The maximum sensing length and spatial resolution of the DAS system are 10 km and 6m, respectively. A field test of the DAS system using a single-mode telecommunication fiber cable with a length of 430 m for surface seismic measurement is presented. In the test, a series of conventional 3C-geophones are utilized as a criterion for comparison. Through the raw data absence of processing, preliminary wave, consistent with geophones, are clearly described, which means that the DAS system is capable of surface seismic detection.
