Using Alternative Aperture Geometry Horn Antennas in Wide-Band Multifrequency Measurements
Application of horn antennas in non-destructive testing by multifrequency reflectivity measurements has several advantages in comparison with simple antennas such as open-ended waveguide, in particular, higher gain and narrower directional characteristic. However, having two reference discontinuitie...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Application of horn antennas in non-destructive testing by multifrequency reflectivity measurements has several advantages in comparison with simple antennas such as open-ended waveguide, in particular, higher gain and narrower directional characteristic. However, having two reference discontinuities hinders from using them for the purpose because of superposition of echoing characteristics being retrieved. General solution lies in extracting single echoing characteristic whether by mathematical post-processing measurement results or by strong reducing one of reference discontinuity reflectivity levels by altering discontinuity's geometry, that is the subject of this paper. |
