By moving two independent monostatic single-antenna radar units to the new standoff positions from the wall, the unknown parameters can be determined; then the exact positions of the moving target are obtained with known wall parameters. The algorithm corrects for the shift of the target location due to wall parameters ambiguities. The advantage is that it performs well estimation not only to one parameter unknown, but also to both. Simulation results show that all unknown wall parameters can be estimated exactly. Once wall parameters are determined, through-the-wall radar can be placed in a stationary position to track moving targets, which is very important for detection in security.","PeriodicalId":409971,"journal":{"name":"2007 International Conference on Microwave and Millimeter Wave Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129438546","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}

The antenna is composed of a circular microstrip patch and a semicircular arc cut on the ground of the microstrip line. By embedding a simple arc-shaped slot in the circular microstrip patch, an ultra- wideband (UWB, 3.1-10.6 GHz) operation with a notched frequency band can be obtained. The arc-shaped slot has a length of about one-half wavelength of the desired notched frequency. The measured results also show that the proposed antenna has stable radiation patterns over its whole frequency band. This kind of band-notched UWB antenna requires no external filters and thus greatly simplifies the circuit design of the communication system.","PeriodicalId":409971,"journal":{"name":"2007 International Conference on Microwave and Millimeter Wave Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116400507","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}
