Pipeline secure monitor can finish early monitor,loc at ion and advance alarm for the threatening actions to pipeline security.The key technology is to accurately classify and recognize the targets around the pipel ine.Because moving targets over ground generate a succession of impacts,the so il disturbances propagate away from the source as seismic waves.The seismic sig nals obtained from many separate geophones.To recognize the target and improve the radio of recognition,the D-S evidence theory was used to fuse the data.Th e data characters were investigated and processed by means of multi-sensors dat a fusion,feature extraction,data association and etc.The characteristic fusio n finished in the decision level.The experiments indicate this data fusion meth od is effective to improve these different targets recognition.The result is be tter than single sensor.
