METHOD OF MEASUREMENT OF THE POLARIZATION MATRIX OF THE OBJECT SCATTERING Russian patent published in 2017 - IPC G01S13/00 G01R29/08 

FIELD: radio engineering, communication.

SUBSTANCE: method of measuring polarization matrix scattering object when sensing at a single carrier frequency by orthogonal polarizations simultaneously emit respective orthogonal over radio structure is then received at the same time all the orthogonally polarized components reflected by the object radio signals, output signals each corresponding on receiver channel polarization is fed to the filters, each of which is aligned with one of the radio signals emitted, the measurement is carried out in two or more sensing period. As the emitted radio signals on orthogonal polarizations, a pair of signals, the encoded additional sequences that vary from one period to the probe so that the two additional sequences are developed, and one of their addition is inverted and then compressed matched filters in each of the periods of sensing signals are combined and the parameters determined by the combined radio signal corresponding to the polarization matrix elements of the scattering object.

EFFECT: improved accuracy of measurement of the polarization scattering matrix of the object by eliminating the influence of side lobe signals, matched filter is compressed, and by eliminating the impact of cross-correlation components due to the passage of signals through uncoordinated filters.
