The filter for horn antenna multifrequency data processing

The transceiver horn antenna used in multifrequency microwave measurements for probing a structure under the test and receiving reflected power has two reference discontinuities. This causes the obtained reflectivity dependency to be a superposition of two similar echo characteristics, so that clearly discerning reflectivity signal peaks and estimating their parameters are mostly impossible in the uniqueness range of the Fourier transform, which is used for viewing the spatial area dependency. The filter for horn antenna multifrequency data processing is designed for extracting the single echo characteristic from this dependency. This facilitates using almost all the uniqueness range, provided that in the far-field region the reflectivity ratio of reference discontinuities and the electric length of the horn do not depend on the distance to the structure under the test.
