Abstract

Abstract: Most conventional ground penetrating radar (GPR) is single polarimetric radar, which can only obtain single polarimetric data, and is difficult to identify the pipeline accurately and quickly in a complex environment. In order to identify the pipelines in a complex environment, we applied the method of full polarimetric GPR to identify the pipeline. We extracted the polarimetric attributes of a single pipeline and the polarimetric attributes of the pipeline influenced by other targets. The results show that the target can be well recognized,although its polarimetric attributes are under the influence of other targets. The method of full polarimetric GPR can get more comprehensive polarimetric information of a target,and can effectively and quickly identify a pipeline in a complex environment.

Key words: ground penetrating radar (GPR), full polarization, H/α decomposition, the pipeline detection
