EVALUATION OF THE OBJECTIVES POLARIZATION DISCRIMINATION AGAINST PASSIVE HINDRANCES WITH THE DEVICE, BASED ON CONSIDERATION OF THE SPATIAL VARIATION OF THE FARADAY ROTATION ANGLE I... by Volodymyr I. Mirnenko, Evgen A.Yufa A. Yufa, Maxim N. Zhuravskij

“…It is assumed that the transmitting antenna is linearly polarized. In order to determine the operability of the device under various conditions and to evaluate its efficiency, the signal-to-noise ratio at the output of the device is calculated in the case where the backscattering matrix of the target and the matrix of the interference element (for example, dipole, angle reflector, etc.) are not diagonal, m .e. when a cross-polarization component appears when the signal from the target or from the interference element is reflected.…”
