The use of SAR technique basically helps in providing improved cross-range or lateral resolution without placing a stringent condition on the antenna beam width. The SFCW system in the present situation is realized using an X band horn antenna, the vector network analyzer (VNA)and associated RF components. An automated 2-D scanner is employed for 2-D movement of the transceiver to collect the measured scattering data from different positions of the target. The proposed SAR technique is then applied to generate 2D and 3D images of the target in terms of the measured scattering data. It is observed that the application of the advanced SAR algorithm to the measured scattering data is able to generate more focused image of the target area as compared to the microwave image obtained using the raw scattering data. The applicability of the proposed technique is tested by detection of various types of metallic and plastic objects hidden behind the scene.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114191151","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}

Radio-Frequency (RF) based 3D imaging provides a low-cost, non-invasive, non-ionizing alternative to present day early diagnostic procedures. In RF imaging, the measured field data from an antenna array is used to predict malignant tissues in the breast profile through reconstruction of the dielectric properties. The reconstruction process entails the solution of a non-linear, ill-posed inverse problem. In this work, a multi-resolution approach is proposed to address the computational challenges of the traditional uniform grid approach. First, the measured scattered field data is fed to a Machine Learning based classifier to localize the dense tissue with coarse accuracy. Using this information, adaptively sized voxels are generated leading to a drastic reduction in the number of voxels and hence the number of unknowns for reconstruction. The reduced problem is solved using a traditional optimization algorithm like the Levenberg-Marquardt (LM) method. Numerical experiments demonstrate that the proposed method has significant advantages both in convergence profile and reconstruction efficiency as compared to that on a uniform grid.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117025236","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}
