On the Phase Centers of the Scattering of Compound Shape Bodies in SHF and Short-Wave Ranges

In this paper the results of the experimental study of the polarization features of the backscattering from the compound shape bodies are presented that could be used for their recognition and their course determination as well. The investigations were carried out using the polarimetric coherent systems of the pulse as well as CW transmitting modes of the millimeter wave band. For the study of the phase parity between the elements of the scattering polarization matrix for the polarimeters utilizing the CW mode transmitting the polarization selectors were developed that provides not only orthogonally polarized component expansion of the received signal and the heterodyne signal injection to the working channel having equal phases as well. In the pulse radar polarimeters we used the pulse-by-pulse switching of the receiving signal polarization and alignment of the electrical length of the signal injection and heterodyne ducts in the channels having orthogonally polarized components.
