Abstract
A new solution is proposed due to the performance declining of long distance distribution vibration detection sensors used at complex environment.The solution takes advantage of vibration signal feature extraction,separation and fusion technique which is widely adopted in radar signal processing field,and accomplishes individual vibration signal restore during a multi-source noise.The field test results are accurate when the sensors are used to check two and four concurrent events.The solution provides technical support to deploy long distance distribution vibration detection sensors at harsh environment.

期刊介绍：
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
