Abstract:

The transceiver horn antenna used in multifrequency microwave measurements for probing the structure under the test and receiving reflected power has two reference discontinuities. This causes obtained reflectivity dependency to be a superposition of two similar echoing characteristics, so that clear discerning reflectivity signal peaks and estimating their parameters is impossible in the most part of uniqueness range of Fourier transform, which is used for viewing the dependency in spatial area. The Filter for Horn Antenna Multifrequency Data Processing is designed for extracting single echoing characteristic from said dependency. This allows productive using almost all the uniqueness range provided that in the far-field region the reflectivity ratio of reference discontinuities and electric length of the horn do not depend on distance to structure under the test.
