Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a system and method for estimating highway interference for distributed optical fibers. Background technique [0002] Since any position of the optical fiber is a sensing unit in the distributed optical fiber sensing system, it can obtain the spatial distribution state and time-varying information of the measured parameters over the entire length of the optical fiber. Distributed optical fiber sensing system can realize large-scale monitoring, and has a very important position in many optical fiber sensors. It is the most mature technology and the most widely used category, showing a good application prospect. [0003] The interference of highway vehicles to distributed optical fiber measurement vibration is relatively large, so a complete interference estimation system is required to effectively estimate the interference parameters of highway vehicles to di...
