Abstract EN
This paper mainly focuses on the representable problem of Φ-OTDR distributed vibration signals.
The research included a signal extraction part and a signal representation part.
Firstly, in order to extract the better Φ-OTDR signal, the time-domain data should be fully preserved.
The 2D-TESP method is used to extract data in this paper.
There are 29 characters in the traditional TESP method.
The characters’ number is reduced from 29 to 13 and the characters’ dimension is expanded from 1 to 2 in the 2D-TESP method.
Secondly, in order to represent Φ-OTDR signal better, the characteristics of Φ-OTDR data and damped vibration signals are combined in the paper.
The EMD method and the NMF method are combined to form the new method in the paper.
Some parameters in the proposed method are optimized and adjusted by GA method.
After Φ-OTDR data is represented by the proposed method, there is excellent performance both on the length dimension and on the time dimension.
Lastly, some experiments are carried out according to the physical truth in this paper.
The experiments are carried out in the semianechoic room.
The methods of the paper have better performance.
The methods are proved to be effective through these experiments.
