Terahertz radar of image to study the properties of materials

DOI №______

Abstract

The possibility of 3D radar calibration is studied in the exploring of material properties to the example of plexiglas, depending on the distance between the sample and the antenna using an absorber. The results of preliminary studies indicate the possibility of measuring the thickness of the material. On the calibration, a small metal plate and several measurement cycles for averaging the noise were used. It is shown that the accuracy of measurements is influenced by the width of the radiation pattern, the reduction in the number of measurement cycles at one point, the accuracy of positioning and moving the head during the measurements, and the time interval between the calibrations.

Keywords: absorber; digital spectral analysis; electromagnetic simulator; horn antenna.
