A mathematical model for an existing harmonic transponder tag is developed to facilitate the evaluation of these techniques. This is done using a Taylor series approximation, which is then verified using laboratory measurements. The measurements show that the effective isotropic radiated power of the harmonic reflections is proportional to the square of the incident power density. Finally, a time-domain simulation of the transponder tag in a typical radar channel with non-idealities is described. To render the computation more efficient, a complex baseband method is developed, which takes the transponders' memoryless nonlinearity into account.","PeriodicalId":325654,"journal":{"name":"Proceedings of the 6th International Conference on Telecommunications and Remote Sensing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130315466","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}

Two comparable antenna designs, one with an air core and other with dielectric-loaded core is presented and their performance is compared for different scenarios. The laboratory experiment results reveal that both antennas have major radiation lobes along the axis of the antenna center conductor. The experimental testing reveals that the air-core antenna outperforms the dielectric-loaded core antenna when in air but it falls behind once it is tested in the borehole. The experimental work was performed in a shallow borehole that intersects sediments. A reflector, located at the transition between fluvial sands and lacrustine sand and clays was detected at a distance of 1.5 m. The air-cored antenna was unable to propagate energy forward and had strongest coupling to a surficial shallow casing.","PeriodicalId":325654,"journal":{"name":"Proceedings of the 6th International Conference on Telecommunications and Remote Sensing","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115923951","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}
