Abstract
The invention discloses a leakage identification method based on a DAS, which aims at reducing the cost of laying sensing optical fibers, aims at accurately identifying and accurately positioning leakage points in intervals when the sensing optical fibers are laid at intervals, and uses a signal extraction enhancement means combined with signal space wave number information. And the leakage point positioning precision of the correlation analysis method is improved. The invention also provides a leakage identification device. The method provided by the invention can solve the problems of low signal-to-noise ratio and mode aliasing in the leakage identification process.
