Abstract

A multi-dimensional spatial positioning system and method for disturbance source. The system includes a distributed-optical fiber sensor, a sensing optical fiber, a coordinate system, a disturbance source to be monitored, a first signal group, and a second signal group. The disturbance source is positioned by combining an array signal processing method with the distributed optical fiber sensor, using different laying manners for the sensing optical fiber and a certain number of flexibly selected sensing units distributed a certain distance from each other along a line, and combining with a special signal processing method, thereby realizing a function of being capable of monitoring multi-dimensional spatial position information of the disturbance source in real time in both short and long distances.
