TOMOGRAPHIC IMAGE RECONSTRUCTION USING PARALLEL-BEAM PROJECTION WITH MICROWAVE FREQUENCY FOR HOLLOW TREES DETECTION

TOMOGRAPHIC IMAGE RECONSTRUCTION USING PARALLEL-BEAM PROJECTION WITH MICROWAVE FREQUENCY FOR HOLLOW TREES DETECTION

Tomography is a technique for reconstructing an image of object cross-section using emitted waves. In this study, frequency selection and measurement systems for microwave tomography are proposed. Frequency selection is intended to determine the characteristics of microwave tomography using parallel...
