摘　　要：常规探地雷达大多数是单极化雷达,单极化雷达只能获得单极化数据,对复杂环境中管道准确快速地识别比较困难。为了解决此问题,本文采用了全极化探地雷达识别管道的方法,提取了单一管道目标、多个管道目标中任何一个管道目标和受其他目标影响的管道目标的极化属性。结果表明,全极化探地雷达技术对处于极化属性受到影响环境下的管道目标均能较好地识别。因此,全极化探地雷达能够获得更加全面的目标体极化信息,有效地解决了复杂环境中管道准确快速识别比较困难的问题。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.
