| Abstract | 本发明属于天线技术领域，具体提供了一种大型波束波导天线抗风扰的指向误差补偿方法，其步骤包括：(1)计算等效馈源位置所需横向位移；(2)确定天线波束波导系统的反射镜组合，初步估计馈源虚像镜面所需位移；(3)根据馈源虚像所需镜面位移及驱动器的行程，具体确定各个反射镜镜面尺寸；(4)确定其中的反射镜一结构，根据方位方向馈源虚像所需位移，计算反射镜一方位方向驱动所需位移；(5)根据俯仰方向馈源虚像所需位移，计算反射镜一俯仰方向驱动所需位移。本发明采用对波束波导系统中的镜面位置实时可调的方法，来改变主面系统中等效馈源位置，从而补偿由风扰造成的主面系统变形而导致的天线指向偏差，提高了天线的指向精度。 |
| Other Abstract | The invention belongs to the technical field of antennas, and particularly relates to an anti-wind-disturbing pointing error compensation method for a large beam waveguide antenna. The method includes the steps of (1) calculating a transverse displacement needed by the position of an equivalent feed source, (2) determining a reflection mirror combination of an antenna beam waveguide system and estimating a displacement needed by a mirror surface of a feed-source virtual image primarily, (3) specifically determining sizes of mirror surfaces of all reflection mirrors according to the displacement needed by the mirror surface of the feed-source virtual image and the stroke of a driver, (4) determining the structure of the first reflection mirror, and calculating the displacement needed by azimuth direction drive of the first reflection mirror according to the displacement needed by the feed-source virtual image in an azimuth direction, and (5) calculating the displacement needed by pitching direction drive of the first reflection mirror according to the displacement needed by a feed-source virtual image in the pitching direction. According to the method, the position of the equivalent feed source in a primary surface system is changed in the way that the positions of the mirror surfaces in the beam waveguide system are adjustable in real time, and accordingly pointing deviation of the antenna caused by deformation of the primary surface system as a result of wind disturbing is compensated and pointing accuracy of the antenna is improved. |
