The radar modules have been used originally in process industry for fill level measurements. In this contribution we will show that these industry radar modules for C-Band and K-Band frequencies, can be adapted in order to apply them for sensing buried objects. The measurement of the reflected pulse unveils information about buried objects and the structure of the ground surface. The radar signal is evaluated by subsampling the carrier modulated Gaussian pulses. The envelope of the consecutive samples, that represents a stretched replica of the high frequency radar signal, is digitized and transferred to a post processing computer. Post processing techniques have been applied on the measured data in order to increase the image resolution. Experiments carried out with the radar modules underline their capability for detection and remote sensing of subsurface objects.","PeriodicalId":130006,"journal":{"name":"2011 6th International Workshop on Advanced Ground Penetrating Radar (IWAGPR)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116930192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
