Abstract:

A non-invasive geophysical exploring method,ground penetrating radar (GPR) technique was used to detect subterranean termite nests. With a simulation experiment in which the GPR was used to detect the target's profiles of artificially buried metal pipes and termite carton nest, linear regression models between target and image sizes were established. Two and three dimensional nest images were created. After field survey,excavation was conducted to verify targets based on representative GPR profile data,features of GPR profiles of metal objects,voids,tree roots and termite nests were describe. The average error rate in determining nest size was 1.93% using the linear correlating model. Our study showed that GPR system was a useful assistant tool for monitoring and prevention subterranean termite.
