METHOD OF MEASUREMENT OF OBJECT POLARIZATION SCATTERING MATRIX WITH DISTORTION COMPENSATION Russian patent published in 2017 - IPC G01S13/00 G01S7/41 

FIELD: radio engineering, communication.

SUBSTANCE: method of measuring object polarization scattering matrix with distortion compensation when sensing at one carrier frequency by orthogonal polarizations respective structure orthogonal radio signals are simultaneously emitted, all orthogonally polarized components of radio signals, reflected from the object, the output radio signals of each receiver channel, equivalent in polarization receiver channel, is fed to the filters, each of which is associated with one of the emitted structure orthogonal radio signals. To compensate for the distortion caused by mistuning of used transmission and reception channels, the signals at the outputs of matched filters are multiplied by weighting factors, which are found prior to the radiation of probing signals by the location object on the basis of the analysis of the results of radar station operation, and then the parameters of radio signals are measured at the outputs of multipliers. The radio signals determine the relevant elements of the object polarization scattering matrix. The measured values of the main distribution frame elements of the object polarization scattering matrix are combined.

EFFECT: increase in the accuracy of measuring the object polarization scattering matrix by compensating for the resulting distortions.
