Problems solved by technology

[0004] The traditional X-Y antenna pedestal requires two-axis rotation of the antenna pedestal and multiple feeds to achieve overhead tracking. Therefore, in order to ensure high reliability of overhead tracking, the structure of the existing X-Y antenna pedestal is generally large in size, Heavy weight, large moment of inertia, high cost, very inconvenient installation and transportation, difficult to achieve tasks such as quick adjustment, assembly, transportation, and locking of the antenna

Abstract

The invention discloses an X-Y-axis antenna base and an antenna system. The X-Y-axis antenna base comprises an X-axis mechanism and a Y-axis mechanism which are fixedly connected. A support arm is fixedly disposed on the Y-axis mechanism. An X-Y-type antenna base is connected to an antenna mechanism through the support arm. The X-axis mechanism includes an X-axis and a first brake module. The Y-axis mechanism includes a Y-axis and a second brake module. The X-axis and the Y-axis are orthogonally coplanar. The first brake module controls the rotation state of the X-axis. The second brake modulecontrols the rotation state of the Y-axis. The X-axis and the Y-axis mechanism are fixedly connected to each other. The X-axis can drive the Y-axis mechanism to rotate. The Y-axis can drive the support arm to rotate. The X-axis and the Y-axis are orthogonally coplanar so as to reduce the overall volume of the X-Y-type antenna base, achieve compact structure, facilitate the transportation of the X-Y-type antenna base, and effectively reduce the moment of inertia.

Description

technical field [0001] The invention relates to the technical field of radar antennas, in particular to an X-Y axis antenna base and an antenna system. Background technique [0002] The overhead tracking of the antenna pedestal is a technical means for real-time and continuous tracking of satellites. It is mainly used in polar-orbiting satellites, inclined-orbit synchronous satellites, and "communication in motion" equipment. [0003] At present, the widely used antenna base mechanism forms are mainly pitch and azimuth antenna bases and X-Y antenna bases. For the pitch and azimuth antenna base, due to the blind cone area in the operation process, it cannot effectively achieve overhead tracking, which is limited in practicability; the X-Y type antenna base is set at X because its blind cone area is not at the top. Below the axis, it avoids the disadvantages of using the pitch and azimuth antenna base, and can meet the requirements of overhead tracking of the antenna. [000...
