TARGET IDENTIFICATION PROCEDURE AND FACILITY FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: radiolocation, identification of objects by polarization characteristics of reflected signals. SUBSTANCE: target identification procedure by polarization characteristics consists in irradiation of target by sequence of HF signals which includes at least one signal with linear vertical polarization and at least one signal with linear horizontal polarization, in reception of reflected signal on each polarization, in split of received signal into components with vertical and horizontal components and in processing of polarization-split components. In correspondence with invention there is employed parabolic antenna which cross-polarization directivity diagram beyond limits of region located close to optical center of antenna distributes HF signal cophasally in antenna aperture according to cross drifts of its polarization basis and with equal amplitudes. Polarization-split components are process by way of formation of signal corresponding to difference of polarization-split components with the use of differential single T bridge. Facility for target identification includes antenna, polarization former, polarization separator, phase compensator, valve-flange, antenna switch, differential single T bridge. EFFECT: expanded range of method and facilities ensuring simplicity of target identification. 3 cl, 2 dwg
