摘要: Distributed fiber sensing technology based on a Brillouin optical time domain reflectometer is widely applied for health monitoring in engineering. However, it cannot perceive quick external interference. In this paper, we propose to use polynomial fitting the inverse of an incomplete spectrum and find peak frequency by statistical analysis. Simulation results show that obtained our method only 1.096 MHz higher than using Lorenz whole discrete spectrum. The has high accuracy, good repetitiveness, stability helpful situations with interference lasts short time.
