FIELD: antenna equipment engineering.
SUBSTANCE: antenna device with linear polarization contains two-axial cardan suspension, in internal frame of which controllable three-level gyroscope is mounted, while internal and external frames of suspension are mechanically connected to parabolic mirror by means of rigid joints and rods, which mirror is capable of rotating relatively to radiation center of immovable multi-channel irradiator, rigidly held on base of antenna device, two rotating electro-engines of appropriate frames of cardan suspension, controlled by signals, formed in internal digital computing device, rotation angle indicators of external and internal frames, mounted on base of antenna device and on external frame of cardan suspension, respectively. Additionally provided are two-channel gyroscopic angular speed indicator, mounted on internal frame of cardan suspension, three one-component accelerometers with mutually orthogonal sensitivity axes, mounted in internal frame of cardan suspension, lesser hyperbolic latticed mirror, mounted by means of calibrating mechanisms and immoveable wave ducts on base of antenna device, its focus, remote relatively to parabolic mirror, coincides with focus of parabolic mirror, and in its other focus, center of emission of immoveable multi-channel irradiator of direct irradiation of main range with linear polarization is positioned, which linear polarization coincides with direction of conductors, forming grid of lesser hyperbolic mirror. Emission center of immovable multi-channel irradiator of direct irradiation of more short-waved wave range with orthogonal polarization relatively to direction of conductors of grid of lesser hyperbolic mirror is mounted in farther focus of lesser hyperbolic latticed mirror. Mechanical link of external and internal frames of two-axial cardan suspension with parabolic mirror provides for equality of appropriate rotation angles of frames and mirror relatively to base of antenna device.
EFFECT: increased self-guiding precision of carrier, increased angular resolution capacity and interference resistance of self-guiding system under conditions of interfering effects with simultaneous expansion of priming angles.
